Application of pressure sensor in petrochemical industry

With the continuous development of science and technology, the requirements for on-site monitoring are becoming higher and higher in various industries, and a large amount of information needs to be collected for timely feedback. In this process, the pressure sensor plays a vital role.

Pressure sensors are now widely used in process control systems, pressure calibration instruments, refrigeration equipment and HVAC control, hydraulic systems and valves, level measurement, biomedical instruments, ships and marine, aircraft and avionics systems, weapons and equipment, and petrochemicals Industry and many other fields.

Pressure sensor is one of the most used measurement devices in the automatic control of the petrochemical industry. In large-scale chemical projects, almost all applications of pressure sensors are included: differential pressure, absolute pressure, gauge pressure, high pressure, differential pressure, high temperature, low temperature, and remote transmission flange pressure sensors of various materials and special processing. .

The demand for pressure sensors in the petrochemical industry is mainly concentrated on three aspects: reliability, stability and high accuracy. Among them, reliability and many additional requirements, such as range ratio, bus type, etc., depend on the structural design of the transmitter, the level of mechanical processing technology and the structural materials. The stability and measurement accuracy of the pressure sensor ensure the stability and high accuracy of the pressure transmitter. Corresponding to the measurement accuracy of the pressure transmitter is the measurement accuracy and response speed of the pressure sensor. Corresponding to the stability of the pressure transmitter is the temperature and static pressure characteristics of the pressure sensor and long-term stability.

It can be seen that the demand for pressure sensors in the petrochemical industry is reflected in four aspects: measurement accuracy, fast response, temperature characteristics and static pressure characteristics, and long-term stability.

With the continuous development of science and technology, the production technology books of pressure sensors are also constantly updated. The current pressure sensors can well meet the demand for pressure sensors in the petrochemical industry.

Pressure sensors applicable to the petrochemical industry:

PCM340 non-cavity flat membrane pressure transmitter with strong anti-vibration ability and good stability, adopts high-precision foil strain gauge, non-cavity measuring diaphragm, especially suitable for measuring liquids with high viscosity. The product adopts an improved and optimized installation structure, which makes the product have good anti-vibration ability. Equipped with a variety of characteristic amplifier circuits, such as anti-interference, high temperature resistance type, intrinsically safe explosion-proof type, etc., making this type suitable for oilfield, food and other measurement and control occasions.

PCM450 flange flat film pressure transmitter adopts international standard flange as interface standard, which can realize user's on-site flange installation. Because the exposed diaphragm directly feels the pressure, it is easy to clean, and it can meet the requirements of harsh working conditions such as moisture resistance, waterproof, and explosion protection. This series of products are widely used in industrial process control, petroleum, chemical, metallurgy and other viscous media containing particles.

PCM3051S-LT, RD intelligent flange pressure, differential pressure transmitter is a world-leading high-performance pressure transmitter carefully developed using the world's most advanced single crystal silicon pressure sensor technology and patented packaging technology. This product adopts patented double overload protection diaphragm design and internal circuit anti-surge protection design, which can accurately measure the gauge pressure, absolute pressure, flow rate, vacuum degree, liquid level and density.
