WMT18082 Ex-proof Temperature Switch (Controller) is a type of explosion proof product for temperature 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 temperature sensor (RTD or thermocouples) into standard output by high precise A/D microprocessor processing. It can display the temperature, and outputs the analog transmission and switching controllers. This smart digital switch is flexible, safe, reliable easy to operate. It is widely used in hydroelectric, petroleum, chemical, mechanical, hydraulic and other industries.
