Function of a Capillary Thermostat
Bulb and capillary thermostats have a fluid filled bulb and respond quickly to change in temperature. When temperature rises the bulb fluid expands via the capillary tube to an expandable diaphragm or bellows to open or close the contacts.Capillary thermostats are used to control heating elements. Based on the set temperature, the sensor closes as the temperature rises and opens as the temperature falls.
