Temperature Switches

Temperature Sensors and Switches

Temperature sensors and switches are used for the effective protection of internal combustion engines, pumps, compressors, gearboxes, reservoirs, and industrial power plants.  For temperature sensing of non-conductive oils and refrigerants, open thermistor sensors are commonly specified.

Gems Sensors & Controls designs and manufactures several models of highly rugged temperature switches and open thermistor sensors. Compact, hermetically sealed Gems temperature switches utilize a high-pressure liquid-filled capillary for the effective sensing of temperature changes. As temperature increases, the liquid expands, leading to an increase in capillary pressure. Open thermistor sensors feature a proprietary fused glass hermetic seal, along with an axial feed through design, for exceptional high-pressure and temperature sensing capabilities. Their unique construction allows for the effective monitoring of level and temperature parameters within a single measurement device.

In addition, a custom solution can be designed and manufactured in OEM volumes, often with lead times shorter than many industry off-the-shelf solutions.
