Single/multi Gas-Gas Detector-Industrial Gas Concentration Detector

Posted on by

Gas detector is also called Gas concentration detector, which supports single gas detection or 1~4 multi gas detection. Gas detector is a flammable gas monitor with modular design, intelligent sensor detection technology, overall explosion-proof (d) structure, and fixed installation. With dot-matrix LCD liquid crystal display, three-wire 4~20mA analog and RS485 digital signal output. It can be configured as programmable switch output and other modules, and provide customized products according to user needs. It also supports functions such as output signal fine-tuning, which is convenient for system assembly network and maintenance.

FAQ

Yes, there is a device called a gas detector that is designed to detect the presence of gases in an area.

Gas detectors can identify various types of gases, including natural gas, carbon monoxide, propane, and many toxic or combustible gases. The specific gases a detector can identify depends on its design and sensors.

Yes, when maintained and calibrated properly, gas detectors are effective in sensing and alerting about the presence of specific gases. However, it’s important to choose the right detector for your needs and to regularly check its functionality.

For homes with gas appliances or heating, it’s crucial to have a carbon monoxide (CO) detector. If you have concerns about potential gas leaks, consider a combined CO and natural gas detector. Always place detectors in recommended locations and check their batteries regularly.

Industrial Gas Detector is an instrument specially designed for gas safety concentration detection. The working principle of Gas Detector is mainly to convert the physical or chemical non-electrical signals collected by the gas sensor into electrical signals, and then rectify and filter the above electrical signals through external circuits. And through these processed signals, the corresponding modules are controlled to realize gas detection.

The core of the Gas Detector is the built-in sensor component, which has different detection technology principles based on the different gases it detects.

We at Sino-Inst are professional Gas Detector manufacturers. We have long provided Single/multi Gas-Gas Detector-Industrial Gas Concentration Detectors to various industries. If you need to monitor gas concentration, please feel free to contact our sales engineers!

Dew Point Meter Analog output calculation

Analog output calculation

For example, the range is -40~+80 degrees Celsius, and the output is 4~20mA. When the output signal is 12mA, calculate the current temperature value.

This temperature range has a span of 120 degrees and is represented by a 16mA current signal.
120 degrees/16mA=7.5 degrees/mA, that is, a current of 1mA represents a temperature change of 7.5 degrees.
Measured value 12mA-4mA=8mA, 8mA*7.5 degrees/mA=60 degrees.

60+(-40)=20 degrees, the current temperature is 20 degrees.

Voltage output signal conversion calculation

For example, the range -40~+80 degrees Celsius, 0-10V output, when the output signal is 5V, calculate the current temperature value.

The span of this temperature range is 120 degrees, expressed by 10V voltage signal, 120 degrees/10V=12 degrees/V.
That is, a voltage of 1V represents a temperature change of 12 degrees, and a measured value of 5V-0V=5V, 5V*12 degrees/V=60 degrees.
60+(-40)=20 degrees, the current temperature is 20 degrees.

The above calculations are generally used for debugging and analysis. When actually connected to the PLC/DCS system, the ADC conversion and digital display are performed by the PLC or DCS
The system is complete.

Integrated Zirconia Oxygen Analyzer

Posted on by

Zirconia Oxygen Analyzer is an analyzer used to monitor and control the oxygen concentration of flue gas in combustion gases, boilers and industrial furnaces. Widely used in industrial fields that require a lot of energy – such as steel plants, power plants, petroleum and petrochemical, ceramics, paper, food or textile industries, as well as various incinerators and medium/small boilers, etc. Zirconia Oxygen Analyzer helps save energy. It can also reduce CO2, SOx, and NOx emissions by controlling complete combustion. Contribute to the protection of the earth’s environment, prevention of global warming and air pollution.

Frequently Asked Questions

Zirconia oxygen analysis is a method of measuring the oxygen content in a gas sample. The technology is based on the fact that zirconium dioxide, or zirconia, is an oxygen ion conductor at high temperatures. When a voltage is applied across a zirconia cell, it drives oxygen ions from one side to the other, creating a current proportional to the oxygen concentration in the gas sample. This technology is widely used in a variety of industries, including combustion control systems, car emission controls, and environmental monitoring.

A zirconia oxygen analyzer usually operates at a high temperature, typically around 700 to 800 degrees Celsius. At these elevated temperatures, zirconia becomes a good conductor of oxygen ions. This high temperature is crucial for the operation of the device, as it facilitates the necessary electrochemical reactions that allow oxygen ions to move across the zirconia membrane, generating an electrical signal proportional to the concentration of oxygen.

The operation of a zirconia oxygen analyzer is based on the Nernst equation. This equation expresses the relationship between the voltage generated across a zirconia cell and the oxygen concentrations on each side of the cell. Here it is in its simplest form:

E = E0 + RT/4F * ln(pO2(1)/pO2(2))

Where:

E is the voltage across the cell,
E0 is the standard cell potential,
R is the gas constant,
T is the temperature in Kelvin,
F is Faraday’s constant,
pO2(1) and pO2(2) are the partial pressures of oxygen on the two sides of the cell.

Zirconia and titania O2 sensors both serve the same purpose of measuring oxygen levels, but they operate using different principles and have different characteristics:

Zirconia sensors rely on the Nernst effect, which creates a voltage difference proportional to the logarithm of the oxygen pressure difference across a zirconia cell. Zirconia sensors are excellent at providing accurate and reliable measurements and are commonly used in automobile exhaust systems and industrial applications.

Titania sensors, on the other hand, change their electrical resistance according to the concentration of oxygen. When exposed to a rich mixture (more fuel, less oxygen), the resistance of the titania sensor increases; when exposed to a lean mixture (less fuel, more oxygen), the resistance decreases. This type of sensor is simpler and more robust but provides less precise measurements compared to zirconia sensors.

Standard gas:

National secondary standard material, oxygen in nitrogen. Oxygen content is proportioned according to need. The general standard is 5.0%. Calibrate zirconia oxygen analyzers against known gas standards. Turn on the calibration gas, connect the calibration gas connection hose to the calibration gas inlet of the zirconia probe, and judge whether the zirconia oxygen analyzer is accurate according to the known oxygen content of the calibration gas.

Selection of Zirconia Oxygen Analyzer

1) The flue gas temperature at the recommended installation sampling point

Low temperature type is selected when the flue gas temperature is below 400°C;
When the flue gas temperature is below 700°C, select the warm type;
Choose the high temperature type when the temperature is above 700°C.
If the flue gas contains more corrosive gases, an aspirating oxygen analyzer with a sample gas pretreatment device should be selected.

2) Select the probe length

The total length of the probe refers to the length from the installation flange to the sampling port of the oxygen sensor. The actual total length of the probe should also add 150mm to the length of the junction box.

Probe length = mounting screw distance 100mm + furnace wall thickness + length inserted into the furnace or flue (generally around 400mm)

3) Instrument selection

Oxygen converters can be divided into disc meters and wall-mounted meters according to the installation form. The disc meters include disc vertical meters and disc horizontal meters. The installation position of the wall-mounted meter can be selected at a place close to the oxygen detector and convenient for debugging.

There are four options for the oxygen content of the full scale of the transmitter: 0~5%, 0~10%, 0~20.6% (factory default value), 0~25%, corresponding to the current output of 4~20mA.
