Single Way Sensor TX400048 Digital Temperature Controller

Description of the humidity and temperature controller:

The humidity and temperature controller is maily used for regulating the huimidity and temperature in equipments such as medium-high voltage switchgear, terminal box, ring main unit, packaged substation. It can prevent equipment breakdown due to low or high temperature, also avoid creepage or flashover accident due to damp or condensation.

Working Principle: 

The temperature and humidity controller consist of sensor, controller, heater (or cooling fan), the working principle as below show:

Sensor test humidity information in the cabinet, then pass to controller for analysing. When the temperature and humidity reach or ove than the pre-set value, relay contactor inside controller will close, heater or cooling fan will start working to heat or cool the cabinet. After a while, the humidity and temperature have large differ from the setting value, then the relay contactor open, heater or cooling fan stop working. Except for the basic functions, it has other auxiliary functions like wire-break alarming, transmitting output, 485 telecommunication, forced heating and air blowing etc.
