Practices described pressure sensor

Selection pressure sensor to note when a lot of problems , for example, the pressure sensor range , precision, pressure sensor temperature properties, chemical properties are to be taken , and the pressure sensor operation mode is an important issue to be considered . Such as sensors for gas pressure measurement and measuring the fluid pressure situation is different . Gas is a compressible fluid , increasing wins will be able to store certain compression , decompression time and to the kinetic energy released, the elastic membrane is applied to the sensor shock . Requires a greater pressure sensor overload . Liquid is an incompressible fluid , the pressure Car Temperature Sensor is installed , tighten the screws nor the compressible space will enable the fluid pressure rises above the pressure limit of the elastic membrane , resulting in the elastic membrane rupture . Because of this situation has occurred frequently , it also requires a greater pressure sensor overvoltage capability. Pressure sensor working conditions , such as a large vibration , shock, large electromagnetic interference, sensor propose more stringent requirements. Not only overvoltage capability, and require reliable mechanical seals , anti- loose, sensors are installed correctly . Crankshaft Positioning Sensoritself leads, pins and outer conductor should be electromagnetic shielding and shielding is well grounded. In addition, consideration should be given to the measured fluid pressure sensor media compatibility issues . Elastic membrane structures such as sensors should be spaced with corrosive media , this time picking a stainless steel bellows sensor , the sensor with silicone oil as pressure medium . Sensors to detect flammable, explosive medium pressure, using a small excitation current to prevent sparks elastic membrane rupture , Mars, and increase the ability to withstand the pressure sensor jacket . Only by understanding the operation of the pressure sensor means in order to better select a pressure Car Temperature Sensor , in particular a pressure sensor is now developing rapidly , so understanding pressure sensor operation mode is necessary .
