The pressure switch adopts a high-precision, high-stability pressure sensor and transmission circuit, 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. ATO pressure switch can be widely used in 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 for industrial sites. Pressure switches are widely used in aerospace and military fields, such as M1A1 tanks, Apollo spacecraft, Boeing 747 and other product manufacturing.
