Heating Capillary Thermostats

Remote Sensing Electric Bulb and Capillary Controls

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. Bulb and capillary thermostats provide design engineers flexibility to place the sensor in remote locations. The remote bulb and capillary are available in copper or stainless steel in lengths up to 13 feet. These temperature sensors are used in a variety of applications as temperature and regulating devices or high limit safety sensors.
