The static torque sensor is an instrument that converts the strain generated by the torsional moment into an electrical signal with a linear relationship according to the principle of resistance strain.

This static in a static torque sensor means that the measuring elastomer of the sensor does not participate in relative motion.

It is widely used in testing machines, static torque detection and other test systems, and has been praised by users for its excellent stability, high measurement accuracy and high cost performance.

The flanges at both ends of the reaction torque sensor are praised by users for their excellent stability, higher measurement accuracy, higher cost performance and simpler monitoring methods.

The measuring elastic body of the sensor does not participate in the relative motion. The testing elastic body is subjected to the relative reaction force. During installation, one end is fixed and the other end is subjected to force.

Basic principle of reaction torque sensor:

Using strain gauge electrical measurement technology, a strain bridge is formed on the elastic shaft. 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.
Or directly output standard 4~20mA current signal and 1~5V voltage signal.

The static torque sensor is generally used to test the occasions where the torque changes slowly. The sampling speed is generally lower than 50 times per second. Such as testing the manual torque wrench, the static load torque of the transmission, etc.

The application range of static torque sensor is mainly used in test systems such as experimental machines and static torque detection.

Static torque does not involve acceleration. For example, the torque of the clock spring used to move the second hand is static torque. If the car is traveling at a steady speed, it will develop a rotational static torque because it only rotates, but not acceleration.

The engine produces static and dynamic torque. For example, if you measure torque in a car crankshaft, you measure dynamic torque because cylinder firing and piston rotation of the crankshaft involve acceleration. This static in a static torque sensor means that the measuring elastomer of the sensor does not participate in relative motion.

This static in a static torque sensor means that the measuring elastomer of the sensor does not participate in relative motion. Due to its excellent stability, high measurement accuracy and high cost performance, it has been widely praised in testing machines, static torque detection and other testing systems.

Reaction torque sensor and rotary torque sensor are the two longest used types of torque sensors.

The rotary torque sensor is based on the principle of resistance strain. It transmits wirelessly and non-contact through current collectors, brushes or electromagnetic coupling. It realizes power supply and signal output, and is suitable for intermittent or low-speed measurement. Torque can be measured in both forward and reverse directions.

The rotary torque sensor shaft can be rotated 360 degrees in both positive and negative directions. It mainly measures the high-speed 360-degree rotational torque and static torque. It is generally used to test the occasions where the torque fluctuates violently. It is necessary to implement the capture torque or torque peak. Such as tightening machines, electric wrenches, Motor output torque, engine output torque, drill pipe torque.

The reaction torque sensor converts the strain generated by the torsional torque into an electrical signal that has a linear relationship with it according to the principle of resistance strain. Static means that the measuring elastomer of the sensor does not participate in relative motion. From the understanding of force, this type of test is to test the relative reaction force of the elastic body.

The entire sensor axis of reaction torque sensor cannot be rotated. The rotation angle of the entire sensor is not recommended to exceed 45 degrees, otherwise it may be wound. The reaction torque sensor is generally used to test the occasions where the torque changes slowly. The sampling speed is generally lower than 50 times per second . Such as testing the manual torque wrench, the static load torque of the transmission, etc.

  1. Dynamic torque sensor: mainly used to measure torque and speed in rotating occasions.
    Dynamic torque sensors can be divided into large-range torque sensors, micro-range torque sensors, and disc torque sensors according to their shape and range.
  2. Static torque sensor: mainly used to measure torque in non-rotating situations.

Since the traditional speed and torque sensor has only a single range, when performing a small torque test, the test error will be far greater than the calibration error of the instrument, resulting in no reference value for the test results.

In response to this problem, torque sensor manufacturers divide the large-range torque sensor hardware into dual ranges. When the motor test system performs a small torque test, the test range is switched to a small range file. The advantage of this is to make the test more accurate.

The shaft torque meter is the detection of the perception of torsional torque on various rotating or non-rotating mechanical parts. Torque sensors convert physical changes in torque into precise electrical signals. Torque sensors can be used in the manufacture of viscometers, electric (pneumatic, hydraulic) torque wrenches, which have the advantages of high precision, fast frequency response, good reliability and long life.

A torque sensor is a precision measuring device that measures various torques, rotational speeds and mechanical power.

The main functions of the torque sensor are as follows:

  • It can measure dynamic torque and static torque;
  • The detection stability is very good, the anti-interference performance is very strong, and the accuracy is very good;
  • There is no need to adjust to zero every time you measure, and positive and negative torque can be measured continuously;
  • Its signal output can be operated with you, choose pulse wave or waveform – square wave;
  • It has a wide measurement range: there are 0 to 1000Nm standard to choose from, some non-standard.

Read more about: Static / Reaction Torque Vs. Rotary Torque

The selection of the Shaft Torque Sensor range should be based on the actual maximum torque measured. Usually, a certain margin should be reserved to prevent the sensor from being damaged due to overload.

Calculation formula: M=9550×P/N
M: Torque Unit: N.m
P: Motor power unit: KW
N: Speed Unit: r/min

If the motor you are using is a three-phase induction motor. Due to the large instantaneous torque of the motor, it is recommended that the torque range should be selected as 2-3 times the rated torque.

  1. To transmit the output torque and power of rotating power equipment such as electric motors and internal combustion engines.
  2. Transfer the load torque and input power of generators, fans, pumps, mixers, reducers, transmissions, winches, propellers, drilling machinery and other equipment.
  3. To transmit the torque in the working process of various machining centers and automatic machine tools.
  4. Transmit torque and efficiency generated by various rotating power equipment systems.
  5. Can be used to make viscometers.

  1. The power supply of this series of torque signal couplers is provided by a set of toroidal transformers on the standard strain bridge torque sensor. The induced voltage is rectified on the shaft. The voltage regulator circuit converts it into a high-stability DC voltage.
  2. This voltage is not only supplied to the strain bridge of the standard strain bridge torque sensor as a bridge voltage, but also supplied to the circuit on the shaft as a working voltage. The mV level torque signal detected by the strain bridge is amplified by a high-precision instrumentation amplifier to a KmV level strong signal, and then converted into a square wave signal proportional to the torsional strain through a V/F converter.

Through the wireless transmitter on the shaft, it is transmitted to the wireless receiver outside the shaft non-contact. After demodulation, it is restored to a digital signal with the same frequency as the square wave converted by V/F. The phase difference is less than 1μS, can generally be ignored.

  1. This series of torque sensors can work for a long time because of the transformer induction power supply. It is widely used in torque monitoring of motors, generators, reducers and diesel engines.
  2. Since the output square wave frequency signal is high level, the anti-interference ability is strong. It can be directly sent to the computer or PLC for processing without A/D conversion, which is very convenient to use.
  3. If you need to measure the speed, as long as the special speed sensor and its speed wheel are installed inside the torque signal coupler of this series, the speed signal of 60 square waves per revolution can be measured.

  1. Using two sets of couplings, install the sensor with torque signal coupler between the power source and the load.

The selection of the torque sensor range should be based on the actual maximum torque measured. Usually there should be some margin. Prevent damage to the sensor due to overloading.

Calculation formula: M=9550×P/N

M: Torque Unit: N.m
P: Motor power unit: KW
N: Speed Unit: r/min

If the motor you are using is a three-phase induction motor. Due to the large instantaneous torque of the motor starting. It is recommended that the torque range should be selected to be 2-3 times the rated torque.

According to the connection form of the shaft and the length of the torque sensor, determine the distance between the prime mover and the load, adjust the distance between the axes of the prime mover and the load relative to the reference plane, so that the coaxiality of their axes is less than Φ0.03mm, and fix the original Motives and loads are on the datum plane.

Install the couplings on their respective shafts.

Adjust the distance between the torque sensor and the reference plane so that the coaxiality between its axis and the axis of the prime mover and the load is less than Φ0.03mm, and fix the torque sensor on the reference plane.

Tighten the coupling and the installation is complete.

A torque sensor is a force measuring device and torque measuring tool. It converts a torque measurement (static, dynamic or rotational) into another physical variable. In this case, into an electrical signal that can be measured, transformed and normalized. As the torque applied to the torque sensor increases, the electrical output signal changes proportionally.

Classification of torque sensors:

Dynamic Torque Transducers / Rotational Torque Transducers

Dynamic torque sensors/rotating torque sensors are used in applications where torque measurement must be performed on rotating shafts, engines or stationary electric machines. In this case, the transducer must rotate on a straight line connected to the shaft. Dynamic torque sensors are equipped with slip rings or wireless electronics that transmit torque signals while rotating (non-contact sensors).

Dynamic torque sensors/rotational torque sensors are often used as test tools for electric motors, torque measurement tools, turbines and generators to measure rotational torque. Shaft-to-shaft rotational torque sensors can also be used for feedback control, monitoring torque, analyzing test bench efficiency, and using strain gauges for torque measurements on rotating shafts.

The dynamic torque sensor/rotation torque sensor is also an important part of the dynamometer. Because it provides torque measurement and angular velocity (RPM), it can easily calculate the output power. So it can accurately calculate the electromechanical efficiency of the motor or engine.

Static torque sensor

In some applications, a static torque sensor can be used to measure the torque measurement made by an in-line rotary sensor (static torque measurement) at the point where the torque is transmitted to the ground.

A reaction torque meter has two mounting flanges (flange-to-flange transducers). One face is fixed to the ground or rigid structural member. The other face is fixed to the rotating shaft or rotating element. Rotation creates a shear force between the flanges. This shear force is captured by foil strain gages attached to the sensor beam. It is converted into electrical current through a Wheatstone bridge.

For a given application, static torque sensors (aka torque sensors) are generally not as sophisticated as rotary sensors. So less expensive than rotary sensors. Static torque transducers are often used as torque calibration tools or torque wrench calibration tools. Static torque sensors can also be used as miniature electric torque screwdrivers, allowing engineers to obtain torque feedback in real-time, or to study the torque applied during assembly.

Non contact torque sensor input shaft and output shaft are connected by torsion bar. There are splines on the input shaft and keyways on the output shaft.

When the torsion bar is twisted by the turning moment of the steering wheel, the relative position between the splines on the input shaft and the keyway on the output shaft is changed.

The relative displacement change of the spline and the keyway is equal to the torsion of the torsion rod, which makes the magnetic induction on the spline change. The change of the magnetic induction is converted into a voltage signal through the coil.

The high frequency part of the signal is filtered by the detection circuit and only the torque signal part is amplified.

Due to the non-contact working method, the non-contact torque sensor has a long life and high reliability. It is not easily affected by wear, has a smaller delay, and is less affected by the deflection of the shaft and axial offset. It has become widely used. Mainstream products of the application.

Frequently asked questions

The input and output shafts of the non-contact dynamic torque sensor are connected by torsion bars. The input shaft has splines. The output shaft has a keyway.

When the torsion bar is twisted by the turning torque of the steering wheel, the relative position between the spline on the input shaft and the keyway on the output shaft is changed.

The relative displacement change of the spline and keyway is equal to the twist of the torsion bar. This causes the magnetic susceptibility strength on the spline to change. The change in magnetic susceptibility strength is converted into a voltage signal by a coil.

Non-contact torque transducers have a long life and high reliability due to the non-contact mode of operation. They are less susceptible to wear and have a smaller delay time. Less affected by shaft deflection and axial shift.

Contact torque sensors and non-contact torque sensors are specific to the power supply and signal transmission principle.

For us, the general public, it may be a bit difficult to understand literally. Especially “non-contact torque sensors”.

Literally, it means that no contact is required during the measurement process to produce a result. In fact, they do not. They require contact with the device to be measured in order to detect the result.

The power supply and signal are transmitted directly during the measurement process. They are designed to pass in and out through carbon brushes and slip rings. This causes wear and tear during operation. And can not move at high speed, we usually call it “slip ring torque sensor”. With small size, light weight, fast frequency response, easy to install. The price is also relatively cheap.

“Non-contact” also refers to the operation process of power supply and signal is not contact transmission. Instead, the power supply is passed in through a “non-contact” form. The signal is passed out and the sensor itself is still connected directly to the power supply cable. This “non-contact” is achieved inside the sensor. It is not visible to us.

This “non-contact” can avoid the short life of “contact”. The problem of not being able to operate at high speeds. Because the principle of implementation is different, the size and weight are larger and heavier than those of “contact” sensors, but only in relative terms. With high precision, long service life, high speed operation.

Now the market is basically using “non-contact torque sensor” more. Because the “contact torque sensor” has a life limit. Although the price is advantageous, the total price may exceed the “non-contact torque sensor” after several replacements.

Unless you have special requirements for the sensor. For example, the frequency response time of the signal acquisition, or the size requirements. Either that or the price. These factors aside, we recommend using a “non-contact torque sensor”.

The “non-contact torque sensor” can also measure rotational speed. Optional RS232/485 communication serial port. The signal can be collected and processed, and the scalability should be strong.

A proximity sensor is a non-contact sensor. When a target enters the sensor’s field, it detects the presence of an object (often called a “target”).

Depending on the type of proximity sensor, the sensor can detect objects using sound, light, infrared radiation (IR), or electromagnetic fields. Proximity sensors are used in phones, recycling plants, self-driving cars, air defense systems and assembly lines.

There are many types of proximity sensors, and they all perceive objects in different ways. The two most commonly used proximity sensors are inductive proximity sensors and capacitive proximity sensors.

Inductive proximity sensors can only detect metal targets. This is because the sensor utilizes electromagnetic fields. When a metal target enters the electromagnetic field, the inductive properties of the metal will change the characteristics of the electromagnetic field, thereby alerting the proximity sensor to the presence of a metal target.

Depending on how sensitive the metal is, targets can be detected at greater or shorter distances.

Capacitive proximity sensors are not limited to metal targets. These proximity sensors are capable of detecting anything that can carry an electrical charge. Capacitive sensors are often used for liquid level detection.

Possible targets for capacitive sensors include, but are not limited to: targets in glass, plastic, water, wood, metal, and countless other materials.

A force-torque (FT) sensor is an electronic device that monitors, detects, records, and regulates linear and rotational forces applied to it.

The main functions of the torque sensor are as follows:

  1. It can measure dynamic torque and static torque. Its detection stability is very good, its anti-interference performance is strong, and its precision is very good;
  2. When measuring, it does not need to adjust zero every time, and can measure the positive and negative torque continuously;
  3. Its signal output can be operated with you, choose pulse wave or waveform – square wave;
  4. Its measurement range is very wide: there are standards from 0 to 1000Nm to choose from, and some non-standard ones, such as: 20,000 Nm, 100,000 Nm, and 1 million Nm can be customized as special ranges;
