Rotary torque transducer is a device used to measure the torque of a rotating system. Rotary Torque Transducer (Model:1060) is developed on the basis of strain gauge technology. 1060 Rotary Torque Transducer can measure rotational speed. Such as applied by continuous and pulse electric tools Tightening torque. It can measure both static torque and rotating torque; the range is 0-5000Nm optional, non-standard can be customized.
Both static torque and rotating torque can be measured;
Measurable speed;
High detection accuracy, good stability and strong anti-interference;
The speed can reach 1800-4000 rpm;
The forward and reverse torque can be continuously measured without repeated zero adjustment;
There are no wear parts such as collector rings, so it can run at high speed for a long time;
The strain elastic body has high strength and can bear 150% load;
Strong anti-interference, can be installed in any position and direction;
The sensor part can be used independently from the secondary instrument. It directly forms a torque measurement device with the measurement board, PLC or DCS;
The Rotary Torque Transducer is a sensor with a resistance strain gage as a resistance conversion element. Resistance strain gauges are based on the resistance-strain effect of metal resistance wires. The so-called strain effect refers to a physical phenomenon in which the resistance value of a metal conductor (resistance wire) changes with deformation (elongation or shortening).
A resistance strain gauge is pasted on the elastic body of the dynamic torque sensor to form a Wheatstone bridge. Apply the excitation voltage to the bridge. Under the action of torque, the elastic body deforms. The strain gage thus produces a change in resistance. This makes the bridge unbalanced. The bridge outputs a voltage signal that is linearly related to torque.
There are two speed measurement methods for dynamic torque sensors: photoelectric encoder speed measurement and Hall effect speed measurement. Both methods output 60 pulses in one revolution of the sensor. Torque measurement sensor, and then convert the pulse into frequency square wave output.
The calibration of the rotary torque transducer can be selected in different ways. Calibration in a calibration laboratory or on-site at a test bench. The task of calibrating sensors, such as those used in power test benches. It has always been to transmit the measured torque into the application.
The simplest is to measure the torque transmission performed directly by a torque sensor that resides in the driveline. This is where the calibration of the torque transducer at the factory calibration facility or other on-site calibration laboratory is cited as a reference.
There is another way to calibrate the torque sensor is dynamic calibration. As a dynamic calibration in the narrow sense, it must be recognized that the torque obtained during calibration changes rapidly with time. It corresponds in its dynamics to possible operating time changes. This requires both the determination of the reference torque and the measurement of the output of the sensor to be calibrated when the torque is continuously changing.
Turn on the industrial control host. Open the test software to ensure that the pressure sensor and the motion card are connected stably. The value jump is within the error (0.01gf.cm-0.03gf).
Assemble the auxiliary connector.
Open the software and select the range corresponding to the sensor. Then open the calibration sensor interface and clear the value when the sensor is unloaded.
Select the appropriate weight according to the range of the sensor. For example, 2N.m selects 200g and 100g weights. Tie the weight to one end of the connecting piece, and hang it on one end of the pulley through the rope along the groove circle of the standard piece. Keep the contact state stable without external force.
Click Calibration on the software calibration interface. Enter the torque value for the calibration weight (gravity * arm) and click OK.
Change the direction to wrap the weight and check the reversal force value. If the difference is large (>0.5gf.cm), take the average of the positive and negative force values.
The calibration period is generally one year. If repaired or adjusted during use, recalibrate.
A torque transducer is a device that helps measure how much twisting force is being applied to an object. It’s like a scale that measures how much weight is being applied, but instead of weight, it measures torque.
For example, if you’re trying to tighten a bolt with a wrench, a torque transducer can tell you how much force you’re using to turn the wrench. This can be helpful because over-tightening or under-tightening a bolt can cause problems, so knowing the right amount of torque to use is important.
Torque transducers are used in all sorts of industries, from manufacturing and engineering to automotive and aerospace. They’re helpful for ensuring that machines and equipment are working properly, and for testing the strength and durability of different materials.
Magnetic torque sensors – use magnets to measure the amount of twisting force. The sensor has two parts, one that’s fixed and one that rotates with the object being measured. The changes in the magnetic field can be measured and used to calculate the torque.
Optical torque sensors – use light to measure the twisting force. They work by detecting changes in the polarization or phase of the light as it passes through the material being measured.
Piezoelectric torque sensors – use crystals to generate an electrical charge in response to the force. The charge generated is proportional to the torque being applied.
The type of torque transducer used depends on the specific application and the accuracy and precision required for the measurement.
To measure the torque, you first need to install the torque transducer onto the shaft. This usually involves attaching the sensor to the end of the shaft and making sure it’s securely fastened.
Once the torque transducer is installed, you can start taking measurements. The sensor will detect the twisting force as the shaft rotates, and this information can be displayed on a digital readout or recorded for later analysis.
To get an accurate measurement, it’s important to make sure the torque transducer is properly calibrated and that any external factors that could affect the measurement, such as temperature or vibration, are accounted for.
Overall, measuring torque on a rotating shaft is a relatively simple process that can provide valuable information about the performance and efficiency of a machine or system.

The dynamic torque sensor provided by Sino-Inst is a resistance strain dynamic torque sensor. dynamic torque sensor Torque measurement using strain gauge technology.
A strain bridge is formed on the elastic axis. The electrical signal of the elastic shaft being twisted can be measured by supplying power to the strain bridge. After the strain signal is amplified, it undergoes pressure/frequency conversion. becomes a frequency signal proportional to the torsional strain.
What is the purpose of the force torque sensor?
The force torque sensor is divided into two categories: dynamic and dynamic. Force torque sensor is the detection of torque torque perception on various rotating or non-rotating mechanical parts. And convert the physical changes of torque into precise electrical signals.
The force torque sensor can be used in the manufacture of viscometers, electric (pneumatic, hydraulic) torque wrenches. It has the advantages of high precision, fast frequency response, good reliability and long life.

It can be used to manufacture viscometers, electric (pneumatic, hydraulic) torque wrenches.
Torque sensors are not common in our daily life, but their application is very important. The torque sensor on the car checks the torsional deformation of the torsion bar and converts it into an electrical signal. This electrical signal is transmitted to the electric power steering system under the battery.
The sensor consists of phase splitter units 1 and 2 and a torsion bar. Sensor 1 is located on the steering spindle and sensor 2 is located on the pinion shaft. After the torsion bar is rotated, the two phase splitter units create a relative angle.
The converted voltage signal is transmitted to the electric power steering system. The electric power steering system determines the corresponding working voltage of the EPS steering motor according to the relative resistance. The location of the two cells is also used above.
The electric power steering system only starts the motor to generate electricity when steering is required. This can reduce the fuel consumption of the engine.
It can provide power under various driving conditions. Reduce motor unevenness. The output torque of the motor is assisted by the action of the transmission. Assist system interference, improve the vehicle’s steering characteristics, and improve the vehicle’s active safety.
Without hydraulic circuit, it is easier to adjust and detect. Assembly automation is higher. Different models can be quickly matched by setting different programs. Shorten production and development cycles. No oil leakage problem, reduce environmental pollution.
Electric power steering systems primarily use torque sensors to detect the magnitude and direction of torque or the angle produced by the steering wheel when the driver steers. And convert the required information into digital signal input control unit. Then there is the axis control unit pair.
These signals are calculated to obtain a torque compatible with the driving conditions. And this command is used to drive the motor to work. The output torque of the electric motor is assisted by the action of the transmission.
It’s not hard to see that torque sensors are very important. Damage to the car’s torque sensor directly causes the car to lose its steering assist function during driving. Stiff steering failure.
Such torque sensors are very important in automotive safety issues. The quality of the torque sensor directly determines the safety factor of the car.

The 1050C Dynamic Micro Torque Sensor is suitable for low to mid-range torque measurements. Measurable measuring 0.1/0.2/0.5/1/2/3/5/10 Nm. The maximum speed does not exceed 4000 rpm.
In the dynamic measurement process, the measuring element needs to lead the signal line from the rotating shaft to the control circuit of the fixed housing for signal processing.
If it is led out by the collector ring and the carbon brush (similar to the motor brush), it is a contact type; If the principle of electric, magnetic and optical sensing is adopted, the signal signal is directly transmitted instead of the collector ring and the carbon brush, that is, non-contact measurement.
According to material mechanics, when a torque is applied to a shaft, it will cause a torque deformation. It consists of two physical quantities, one is the torsion angle and the other is the maximum shear stress or strain.
As long as one of them is measured, the torque of the shafting can be obtained according to the relevant calculation formula. Therefore, according to this measurement principle, it can be divided into torsion angle measurement and strain measurement.
Principle of strain measurement.
The most traditional method of strain measurement is to paste resistance strain gauges. With the development of science and technology, in addition to resistance strain gauges, there are many new methods. Such as acoustic surface wave strain measurement, piezoelectric strain measurement and strain measurement by the stretching effect. But the essence of its measurement is to obtain the strain value.
Traditional resistance strain gage torque transducers have strain gages as bridges, glued at 45° and 135° on the elastic axis. When the elastic shaft is torqued, the torsional deformation will lead to the change of bridge resistance, and the change of the strain bridge resistance will be converted into the change of the voltage signal. The signals transmitted from the rotating shaft to the fixed housing mainly include carbon brush contact, electromagnetic induction and wireless transmission.
When the existing torque sensor is used, it is mostly used as a precision torque measurement. After a long time of use, it will cause mechanical fatigue. Therefore, it must be calibrated and tested.
Turn on the industrial control host and open the test software. Make sure that the connection between the pressure sensor and the motion card is stable. The numerical value is within the range of error (0.01gf.cm-0.03gf).
Assemble the auxiliary connectors.
Open the software to select the corresponding range of the sensor. Then open the calibration sensor interface. Clear the value when the sensor has no load.
Select a suitable weight according to the sensor range. Select a small weight for a sensor with a small range, and a larger weight for a large range. For example, choose 200g, 100g weight for 2N.m, choose 500g, 1kg weight for 50N.m. Tie the weight to one end of the connecting piece. Hang it on one end of the pulley through the rope along the groove of the standard piece. Keep the contact state without external force Stablize.
On the software calibration interface, click Allow Calibration. Enter the torque value of the calibration weight (gravity * force arm), and click OK.
Wind the weight in another direction. Check the reverse force value. If the difference is large (>0.5gf.cm), take the average value of the positive and negative force values.
The calibration cycle is normally 1 year. If it is repaired or adjusted during use, it needs to be re-calibrated.
Torque sensors are precision measuring instruments used to measure various torques, revolutions and mechanical thermal efficiencies.
Determine the distance between the prime mover and the load according to the connection form of the shaft and the length of the Dynamic Micro Torque Sensor. Adjust the distance between the prime mover and the load shaft so that the coaxiality of the shaft is less than φ0.03mm. Secure the prime mover and load to the reference plane.
Put the couplings on their respective shafts.
Adjust the distance between the torque sensor and the reference surface. The coaxiality of its axis with the prime mover and the load shaft is less than φ0.03mm. And fix the Dynamic Micro Torque Sensor on the reference surface.
Tighten the coupling and the installation is complete.

Torque is usually referred to as external torque. For example, the rotation of the main shaft of the lathe is an adverse effect of the benefit of the external torque supplied by the power unit. Whereas torque is internal torque. When the spindle bearing is working, the secondary benefit of the cutting speed of the CNC blade to the spindle of the machine tool causes it to cause rotational elastic deformation. It can be used to estimate the torque size.
Torque is the torque that produces a flipping effect or rotational deformation of an object, which is equivalent to the multiplication of the force and the moment arm.
Torque is a parameter that is very frequently involved in rotating dynamic systems. In order to detect the rotational torque, the rotation angle phase angle sensor is used more.
The relatively perfect detection technology of torque test is strain force measurement technology. It has the advantages of high precision, fast frequency response, good stability and long service life.
The special torsion resistance strain gauge is hung on the elastic shaft to be measured with strain force viscose, and a strain force bridge is formed. If the power supply is switched on and off during the supply work to the strain force bridge, the light bulb number that the elastic shaft is twisted can be detected. This is the most basic torque sensor approach.
Dynamic torque transducer: mainly used to measure torque and speed in rotating occasions. Dynamic torque transducers can be divided into large-range torque sensors, micro-range torque sensors, and disc torque sensors according to their shape and range.
The measurement principle of the torque transducer: using the strain gauge electrical measurement technology, a strain bridge is formed on the elastic shaft, and the electrical signal of the elastic shaft being twisted can be measured by supplying power to the strain bridge. After the strain signal is amplified, it is converted into a frequency signal proportional to the torsional strain after pressure/frequency conversion.
Commonly used dynamic torque sensors mainly have the following forms:
Inductive torque sensor: This type of sensor mainly adopts a non-contact measurement method. This kind of torque sensor has a long life, high reliability, and is not easy to be worn.
Potentiometer type torque sensor: This type of sensor can be divided into gear type, torsion bar type, and arm type according to the type. Among them, the torsion bar measurement has a simple structure and relatively high reliability. It was widely used in the early days. Sensors of this type are contacting and suffer from wear that reduces their performance.
Metal resistance strain gauge type: This type of torque sensor is mainly composed of a measuring bridge by pasting strain gauges on the elastic shaft. When the elastic shaft is subjected to torque, it will produce a small deformation and cause the bridge resistance to change. .And the change in the resistance of the strain bridge is converted into a change in the voltage signal to achieve the torque measurement we want.
Torque can be divided into dynamic torque and static torque, which have a great impact on the final assembly of the product. Therefore, in the actual processing process, it is very important to distinguish between the two. Today we are going to tell you the difference between dynamic torque and static torque.
Dynamic torque: It is the peak value displayed in real time during the assembly process when the fastener is tightened. That is, the dynamic torque that the power tool applies to the bolt, overcoming the friction. The axial preload force for the bolts generated by the dynamic torque meets the engineering requirements for the preload force. Generally, the torque value preset by the tool or equipment is the dynamic torque value.
Static torque: refers to the torque required to overcome static friction after a fastener has been fastened and we continue to rotate in the direction of tightening. Generally, the peak torque we measure with an analog hand wrench is the static torque.
Torque sensors are the detection of torsional torque sensing on various rotating or non-rotating mechanical components. Torque sensors convert physical changes in torque into precise electrical signals. Torque sensors can be used in the manufacture of torque wrenches.
Sino-Inst is a manufacturer of Dynamic Torque Transducers. We offer more than 10 types of Dynamic Torque Transducers. Dynamic Torque Transducers can measure a variety of different mechanical power, rotational speed and torque measuring devices.

The dynamic torque sensor is equipped with a speed measuring device, which can measure the rotational speed while measuring the torque. At this time, the torque sensor can also be called a torque speed sensor.

Torque is the force that makes an object turn. The torque of the engine refers to the torque output by the engine from the crankshaft end. It is inversely proportional to the engine speed under the condition of fixed power. The faster the speed, the less torque, and vice versa. It reflects the load capacity of the car within a certain range.
A torque sensor is a device used to measure torque and torque.
The torque sensor is a product composed of a sensitive element and an integrated circuit chip according to the strain of the varistor. The torque sensor processes, shapes and amplifies the torque signal by means of measurement. And transmit the output electrical signal. This is a torque sensor or torque transmitter.
Torque is usually referred to as external torque. For example, the rotation of the main shaft of the lathe is an adverse effect of the benefit of the external torque supplied by the power unit.

And with a microprocessor system. It can realize liquid crystal indication, accumulation, and remote transmission (4-20Ma). Pulse output, upper and lower limit alarm output and other functions. This type of intelligent signal transmitter has high precision and reliability.
The high-pressure metal tube rotameter is the force that the upper and lower ends of the float generate differential pressure to form a rising force when the measured medium passes through the conical measuring tube from bottom to top.
When the lifting force on the float is greater than the weight of the float immersed in the fluid, the float will rise. The area of the annulus will increase accordingly. The fluid velocity at the annulus will drop immediately. The differential pressure at the upper and lower ends of the float will decrease. The float is stabilized at a certain height until the lift force is equal to the weight of the float immersed in the fluid.
The height of the float position corresponds to the flow rate of the measured medium.
The float has a built-in magnet. When the float moves up and down with the medium, the magnetic field changes with the movement of the float.
a. For the local type, the rotating magnet in the local indicator is coupled with the magnetic steel in the float to rotate. At the same time, the pointer is driven to indicate the flow rate at this time through the dial.

What Is Difference Between Rotameter and Flow Meter?
A rotameter is a device that measures the flow rate of liquid or gas in a closed system. It consists of a float that moves up and down in a tube, based on the fluid’s flow rate. The faster the fluid flows, the higher the float rises.
A flowmeter is a device that measures the volume of liquid or gas that flows through it. There are many different types of flowmeters, each designed to measure different types of fluids. For example, positive displacement flowmeters measure the volume of fluid that passes through them, while rotameters measure the rate of flow.
Choosing the right flow meter can be difficult, because there are so many different types available on the market. How do you know which one is right for your specific application?
Sino-Inst offers a wide range of high pressure flow meters that are specifically designed to operate in demanding applications. Our high pressure flowmeters are made from stainless steel construction and are ideal when measuring the flow of fluids under high pressures.
Yes, rotameters are affected by changes in pressure. When the pressure decreases, the rotameter will read a lower flow rate. Similarly, when the pressure increases, the rotameter will read a higher flow rate. This is because the rotameter measures the fluid’s velocity, and changes in pressure will affect the fluid’s velocity. Therefore, it is important to keep the rotameter’s pressure at a constant level if you want to accurately measure the flow rate.
The flow detection element of the rotameter is composed of a vertical tapered tube that expands from bottom to top and a float group that moves up and down along the axis of the tapered tube. Below, I will give you a specific introduction to the classification of rotameters.
Glass rotameter:
Glass rotameters are mainly used in various departments such as the chemical industry, petroleum, light industry, medicine, fertilizer, chemical fiber, food, dyes, environmental protection, and scientific research. Used to measure the flow of single-phase non-pulsating (liquid or gas) fluids. The anti-corrosion glass rotor flowmeter is mainly used for the detection of corrosive liquid and gas medium flow. Such as strong acid, strong acid, oxidant, strong oxidizing acid, organic solvent, and other corrosive gas or liquid medium flow detection.
The main parts such as the liquid plastic tube rotameter cone tube are made of AS, ABS plastic. Has relatively good corrosion resistance. The product also has the characteristics of reasonable structure, small size, lightweight, and the tapered tube is not easily broken. The plastic tube rotor flowmeter can be widely used in chemical, environmental protection, food, and other industrial sectors.
Plexiglass rotameter:
Plexiglass rotameter is divided into panel type plexiglass rotameter and pipeline type plexiglass rotameter.
Plexiglass rotameter also has the characteristics of high transparency, intuitive reading, not easy to break, lightweight, long life, and convenient installation and connection. However, the tapered glass tube of plexiglass cannot be used for organic solvents (such as trichloroethylene, dichloroethane).
Metal tube rotameter:
Metal tube rotameter is divided into on-site pointer indication type and remote transmission type.
Metal float flowmeter is a kind of flow measuring instrument commonly used in industrial automation process control. It has the characteristics of small pressure loss, large detection range (range ratio 10:1), and convenient use. It can be used to measure the flow of liquid, gas, and steam. It is especially suitable for medium flow measurement with low flow velocity and small flow.

What is the difference between a resistance temperature detector (RTD) and a thermocouple? Both RTDs and thermocouples are sensors used to measure heat such as Fahrenheit and Kelvin. These devices are used in a wide range of applications and settings, often presenting people with the dilemma of choosing between RTDs or thermocouples. Each temperature sensor has its own advantages and disadvantages that make it suitable for certain conditions and environments.
RTDs are made of metal wires, usually copper or platinum, that offer resistance to the flow of electricity. The RTD’s resistance changes when its temperature changes, allowing it to be used as a gauge for measuring heat. RTDs are considered to be more accurate than thermocouples as they have a linear relationship between resistance and temperature. RTDs are also less affected by electromagnetic fields than thermocouples.
RTD Working Principle
The full English name of RTD is “Resistance Temperature Detector”, so to be precise, it should be translated as “Resistance Temperature Detector”.
RTD is a special kind of resistor whose resistance value increases as the temperature increases and decreases as the temperature decreases. In industry, this feature is used for temperature measurement, so RTD is also commonly known as “thermal resistance”.
Not all metals are suitable for making RTDs. Materials that meet this characteristic need to meet the following requirements:
The resistance value of the metal has a linear relationship with the temperature change energy;
The metal is more sensitive to temperature changes, that is, the resistance change (temperature coefficient) caused by unit temperature changes is relatively large;
The metal can resist fatigue caused by temperature changes and has good durability;
There are not many metals that meet this requirement. Common RTD materials are: platinum (Pt), nickel (Ni), and copper (Cu).
Take platinum thermal resistance as an example. According to the different resistance values, it can be divided into Pt50, Pt100, Pt200, Pt500 and Pt1000.
The numerical value in the name indicates the resistance value of the thermal resistance at 0°C.
For example: Pt100, indicating that the resistance value of the sensor at 0°C is 100Ω. And Pt1000, it means that the resistance value of the sensor at 0 ℃ is 1000Ω. The resistance value of RTD thermal resistance at different temperatures can be approximated by the formula: R=R0(1+αT).
in: 1) R0 represents the resistance value of RTD at 0℃; 2) a is called the temperature coefficient, which represents the change value of the resistance at unit temperature; 3) T represents the measurement temperature, the unit is °C;
According to the number of lead wires of RTD thermal resistance, RTD can be divided into two-wire, three-wire and four-wire.
The lead of the two-wire RTD is to directly lead out two wires at both ends of the resistor to the temperature measurement module. The temperature measurement module adopts the principle of bridge balance, and RTD is used as one arm of the bridge to measure.
A three-wire RTD can largely eliminate the influence of the sensor leads themselves on the measurement results. The detection accuracy is greatly improved compared to the two-wire system.
Resistance Temperature Detector advantages
No compensation line is required, and the price is cheap; It can transmit electrical signals over long distances; High sensitivity and strong stability; Good interchangeability and high precision.
Disadvantages of thermal resistance:
Although thermal resistance is widely used in industry. But it requires power excitation. Temperature changes cannot be measured instantaneously. The temperature measurement range is limited and the application is limited.
What is Thermocouple?
Thermocouples, on the other hand, are made of two different types of metals that are joined together at the sensor end. The junction between these two metals produces a voltage that is proportional to the temperature difference between the junction and the measuring point. Thermocouples are less expensive than RTDs and can measure a wider range of temperatures. They are also faster at responding to changes in temperature.
Thermocouple Working Principle
A thermocouple is a temperature sensing element. It converts the temperature signal into a thermoelectromotive force signal and converts it into the temperature of the measured medium through an electrical instrument.
The basic principle of thermocouple temperature measurement is that two homogeneous conductors of different compositions form a closed loop. When there is a temperature gradient at both ends, a current will flow through the loop. At this time, there is a seebeck electromotive force – thermal electromotive force between the two ends. This is called the Seebeck effect.
The two homogeneous conductors with different compositions are the hot electrodes, and the end with the higher temperature is the working end. The end with the lower temperature is the free end. The free end is usually at some constant temperature.
According to the functional relationship between thermoelectromotive force and temperature, a thermocouple indexing table is made. The index table is obtained under the condition that the free end temperature is at 0°C. Different thermocouples have different scales.
When a third metal material is inserted into the thermocouple loop. As long as the temperature of both junctions of the material is the same. The thermoelectric potential generated by the thermocouple will remain constant. That is, it is not affected by the access of the third metal into the loop.
Therefore, when measuring the temperature of the thermocouple, the measuring instrument can be connected. After measuring the thermoelectromotive force, the temperature of the measured medium can be known.
Thermocouple Advantages:
High measurement accuracy: The thermocouple is in direct contact with the measured object and is not affected by the intermediate medium.
Fast thermal response time: Thermocouples are sensitive to temperature changes.
Large measurement range: thermocouples can measure temperature continuously from -40 to +1600 °C.
Reliable performance and good mechanical strength.
Long service life and easy installation.
Types and structures of thermocouples
Types of thermocouples Thermocouples include k type (nickel-chromium-nickel-silicon), n-type (nickel-chromium-silicon-nickel-silicon-magnesium), e-type (nickel-chromium-copper-nickel), j-type (iron-copper-nickel) , t-type (copper-copper-nickel), s-type (platinum-rhodium 10-platinum), r-type (platinum-rhodium 13-platinum), b-type (platinum-rhodium 30-platinum-rhodium 6) and so on.
Structural form of thermocouple: The basic structure of a thermocouple is a thermal electrode, an insulating material and a protective tube. Display instrument, recording instrument or computer and other supporting use. In field use, thermocouples suitable for various environments are developed according to various factors such as the environment and the measured medium.
RTD stands for Resistance Temperature Detector, but is also known as PRT (Platinum Resistance Thermometer).
A platinum resistance thermometer (PRT) is an RTD that uses platinum as the sensing element. The most common PRTs are Pt100, Pt500 and Pt1000. (PRT is just a more specific name for RTD)
The first step in identifying an RTD is to find out how many lines it has (2, 3 or 4). Then you can connect the RTD to the multimeter. If it’s a pt100, it should read between 107-110Ω at room temperature. But if it’s a pt1000. You should get a reading of 1007 – 1100Ω. This confirms it’s a Pt1000.
PLEASE NOTE: These readings are standard for new RTD sensors. If the sensor is damaged or used continuously. The readings may vary.
The international standard IEC 60751:2008 defines the resistance versus temperature characteristics of RTDs. Within this standard, in order to provide good interchangeability, there are standards of accuracy. Class A and Class B are two accuracy standards. We provide a tolerance reference table.
We get asked this question a lot, but Pt100s and Pt1000s are two types of RTDs (Pt500s are another type of RTD, but now obsolete).
RTDs use cables because they detect temperature by calculating resistance changes in the material. So you can simply order RTDs with long leads or buy additional cables to expand on your own.
When choosing an RTD, the following factors must be considered:
What temperature are you measuring (surface or immersion in solid, liquid or gas)?
If a fast response time is a must, see the RTD Technology page for various factors in selecting a response time.
Fits the specific dimensions required for your application, such as probe diameter, probe length, compression fittings, required connector types, etc.
Do you need special sheath materials?
Do you need to calibrate the sensor?
Does the sensor need to be resistant to chemicals/abrasion/vibration or any other environmental factors?
Is there high electromotive force (electromagnetic interference) in power switching, rectification or radio waves?
Any other installation considerations? (eg sensor needs to be bent to form before installation)
Distance between sensing area and instrument
Sensing ambient temperature over sensor length
Connection Preferences
Current wiring configurations such as 4-wire sensors will not be compatible with 3-wire configurations.
As a rule of thumb, RTDs should be immersed 4 times the length of the element. (Flat-film elements are typically 2-3mm, while wire-wound elements are about 15mm or more).
We are often asked this question, but Pt100 thermocouples do not exist. A thermocouple is a type of sensor, and a Pt100 is a type of RTD, another type of sensor.
A Pt200 sensor is an RTD, Pt200s have a resistance of 200 ohms (Ω) at 0ºC. The Pt200 sensor is now obsolete and has been replaced by the Pt100 and Pt1000 sensors. The Pt500 sensor is also an outdated RTD.
A Pt500 sensor is an RTD, Pt500s have a resistance of 500 ohms (Ω) at 0ºC. The Pt500 sensor is now obsolete and has been replaced by the Pt100 and Pt1000 sensors. The Pt200 sensor is also an outdated RTD.
Conclusions, which one should you use?
It really depends on the specific application and what is more important: accuracy or speed. If you need to measure very high or very low temperatures, a thermocouple is the better choice. If you need more accuracy, then an RTD is the way to go.
