Welding 316L Stainless Steel Diaphragm G1/F4 Pressure Interface Pressure Switch
Working Principle:
when the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor instantaneously moves, and the switch joint is pushed or disconnected by connecting the guide rod, when the pressure drops or rises. When the rated recovery value is reached, the disc is instantaneously reset, and the switch is automatically reset to achieve the purpose of controlling the measured pressure. Diaphragm pressure switch use high-precision, high-stability pressure sensor and transmission circuit, and then a dedicated CPU modular signal processing technology to realize the detection, display, alarm and control signal output of the medium pressure signal.
Application:
Diaphragm pressure switch can be widely used in petroleum, chemical, metallurgy, electric power, water supply and other fields for the measurement and control of various gas and liquid gauge pressure and absolute pressure. It is an ideal intelligent measurement and control instrument for industrial sites.
