How Temperature Switches Work
A temperature switch works just like a typical electrical switch for on /off application. In this case, the temperature switch operates to switch on or off at discrete process temperatures. A temperature switch consists of two basic parts that you will find in all designs:
(a) A sensing part immersed in the process whose temperature is required to be controlled. The sensing part can either be a sensing bulb filled with a fluid –liquid, gas or a bimetallic strip that uses the differential expansion of two dissimilar metals.
(b) Snap-action contacts that act to switch on electrical power to the device controlling process temperature.
How a Temperature Switch Works
Liquid filled temperature switches comprises a sensing bulb and a bellows element. The bulb is immersed in the process whose temperature is being controlled. The bellows element senses fluid pressure (liquid or gas)
