Adjustable air pressure switch

Description

The pressure switch adopts the pressure sensor and transmission circuit with high precision and high stability, and then uses the special CPU modular signal processing technology to realize the detection, display, alarm and control signal output of the medium pressure signal. Pressure switch can be widely used in the fields of petroleum, chemical, metallurgy, electric power, water supply and other fields to measure and control the gauge pressure and absolute pressure of various gases and liquids. It is an ideal intelligent measurement and control instrument in industrial field.
