WM13082 Ex-proof Differential Pressure Switch (Differential Pressure Controller) is a type of explosion proof product for differential pressure measurement and control with 2 or 5 relay controllers and transmission output of 4-20mA and RS485. It is a full electronic structure, converting the signal from pressure sensor into standard output by high precise A/D microprocessor processing. It can display the differential pressure, and outputs the analog transmission and switching controllers. This smart digital differential pressure switch is flexible, safe, reliable easy to operate. It is widely used in hydroelectric, petroleum, chemical, mechanical, hydraulic and other industries.
