Single Pole Single Throw Adjustable Temperature Switch Circuit For Deep-Fryer



Automatic reset capillary thermostat for water heater  

Capillary thermostat working principle:

The capillary thermostat operates on the principle of fluid expansion. A temperature change in a fluid filled sensing system consisting of probe (also called bulb), capillary and diaphragm capsule, produces a volume change. The resulting movement of the diaphragm acts through a mechanism to operate the micro switch. i.e a single pole, single throw normally closed circuit breaks (opens) on rise of temperature.

Snap-Action Bimetal Disc Thermostat For Ballast Protection


WQS-I series bulb & capillary thermostats are factory calibrated to a predetermined temperature range. This design offers a changeover thermal switch and an optional auxiliary switch that is useful for activation of an alarm or cooling fan. The principles of operation allow this design to be surprisingly cost effective and a leading choice for use in many applications where precision sensing is required while remaining on a tight budget. When temperature rises, the internal fluid located within the bulb expands through a capillary tube to an expandable diaphragm that is configured within the remote thermostat body. This diaphragm assembly activates the electrical contacts at the calibrated temperature set point. The WY-I series is available with a front auxiliary switch as optional.
