High Limit Capillary and Bulb Thermostat
High limit capillary and bulb thermostat has a liquid filled bulb with a temperature set point that expands the diaphragm actuating a snap action switch. Adjustable and fixed temperature models available.
No matter which style or model you choose, all of the thermostats with capillary tube operate using the same physics. A fluid is encapsulated in a metal and when the temperature changes the fluid either expands or contracts. This fluid change moves a diaphragm which is in touch with a snap action switch and either opens or closes a circuit. Our capillary thermostats also offer the option of being ambient compensated to offset the differential in temperature which keeps our thermostat controls more accurate as it’s environment changes.
