What is a gas pressure sensor?

pressure sensor is a device for pressure measurement of gases. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed. For the purposes of this article, such a signal is electrical.

How does gas pressure sensor work?

Gas pressure sensors are pressure transmitters for measuring gas pressure. Gas pressure transmitter refers to a pressure sensor with an output as a standard signal. It is an instrument that accepts a pressure variable to be proportionally converted to a standard output signal. It can transform the physical pressure parameters of gas, liquid and other parameters sensed by the load cell sensor into standard electrical signals (such as 4 ~ 20mADC, etc.). Provide secondary indicators such as alarm indicators, recorders, and regulators for measurement, indication, and process adjustment.
The working principle of the gas pressure sensor is that the pressure directly acts on the surface of the measurement diaphragm, causing the diaphragm to deform slightly. The high-precision circuit on the measurement diaphragm transforms this tiny deformation into a voltage signal that is highly linear and proportional to the pressure and proportional to the excitation voltage. Then use a special chip to convert this voltage signal into an industry standard 4-2OmA current signal or a 1-5V voltage signal.

What is pressure transducer used for?

The main function of a pressure transmitter is to transmit pressure signals to electronic equipment. The pressure is then displayed on the computer. For example, the mechanical signal of water pressure is converted into an electronic signal such as voltage or current (usually 0-5V or 4-20mA). Pressure and voltage or current have a linear relationship. It is generally proportional, so the voltage or current output by the transmitter increases with increasing pressure.
A pressure transmitter is a sensor commonly used in industrial practice. It is widely used in various industrial automatic control environments. Involving water conservancy and hydropower, railway transportation, intelligent buildings, production control, aerospace, military industry, petrochemicals, oil wells, electric power, ships, machine tools, pipelines and many other industries. The pressure transmitter workshop must be in direct contact with the measured medium. Often run in high temperature, low temperature, corrosion, vibration, shock and other environments. Whether it works normally on the job site depends not only on the quality of the product. It also depends on optimized engineering design and reasonable model configuration. And proper installation and maintenance. Pressure transmitters are a key element in the fluid industry.
Pressure transmitters are mainly used in the following areas:
1.Petroleum, petrochemical, chemical industry, supporting with throttling devices. Provides accurate flow measurement and control. Measures pressure and level in pipes and tanks.
2.Electric power, city gas, and other companies. Places requiring high stability and high accuracy measurement.
3.Pulp and papermaking are used in places that require chemical-resistant liquids and corrosion-resistant liquids.
4. Steel, non-ferrous metals, ceramics, used in furnace pressure measurement and other places requiring high stability, high precision measurement and other places. It is used in places where stable measurement is required under strict control (temperature, humidity, etc.).
5. Machinery and shipbuilding, used to strictly control the place where high precision is required for stable measurement.
In general, the pressure transmitter is mainly used to measure the pressure of the medium and the liquid level.
