Product Description
Temperature controller

Principle of performance and Application
When the temperature of the controlled object reaches set value, the 
inner working substance of thermostat sensible bulb produce a moment 
expansion physical phenomenon (the working substance volume large
abruptly),at which connected with the diaphragm of sensible bulb
produce expansion or contraction. Through the leverage to drive 
switch on/off action, the purpose is to achieve constant 
temperature. It is needed to manually reset. WQS series thermostats have temperature-limited accurate, reliable, and large overload current performance characteristics.
