Sensors, Monitors & Transducers

Bulb and Capillary Thermostats target food service equipment.

With Series BC-300, system designers can place system controls in remote locations away from heat source while still mechanically sensing thermal levels. Thermostats use special sealed blend of thermal materials within bulb and capillary assembly to sense heat. Thermal energy heat causes material to expand which opens and closes electrical contacts. Typical applications include professional food...
