At Senasys we design and manufacture a number of high temperature thermostat switches including high limit capillary type thermostats and duct limit controls. A limiting device installed in a piece of equipment with a temperature setting that when the temperature is met either opens or closes a circuit. These are typically installed as a back-up or secondary control to prevent the equipment from exceeding a specified temperature, high or low. For more information please follow the links below, or contact us to speak directly with a customer service representative.

These High Temperature Thermostat Switches have fluid that 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. Common applications include; restaurant equipment, HVAC and other custom applications.
