Pressure sensor operating temperature environment introduction
The application of pressure sensor is very extensive, but according to the different temperature environment, the requirements for the sensor are naturally different. Under normal circumstances, the pressure sensor according to the temperature can be divided into: high temperature melt pressure sensor, high temperature pressure sensor, pressure at room temperature Sensors and cryogenic pressure sensors.
High-temperature melt pressure sensor Its measurement temperature is generally around 400 °C, mainly used in various high-temperature environments where pressure measurement and control are required, such as: plastic and rubber extruders, chemical fiber machinery, boilers, steam, polyester , petrochemicals, etc. High temperature pressure sensors generally have a temperature resistance of 200°C. Normal temperature pressure sensor is generally -20 ~ 85 °C temperature resistance, this type of pressure sensor is generally made of diffusion silicon or ceramic core, mainly used in mechanical engineering and some industrial automation and control areas of hydraulic pressure measurement, such as petrochemical, medical Health, food machinery, beverage processing and other industries. Ultra-low temperature pressure sensors can generally work in -196 °C environment, mainly used for scientific experiments, liquid oxygen, liquid nitrogen, liquid hydrogen, liquid helium and other cooling tanks; aviation, space, ships and other cryogenic storage tanks.
Understand what the temperature range of the pressure sensor can be, and it will be better for us to choose the right product, that is, we will not waste resources and meet our requirements.
