Thermtrol's temperature probethermostats meet the exacting demands of the toughest industrial and commercial applications. Probe thermostats are thermally sensitive bimetallic switches housed in a rugged brass or stainless steel case. The switches are manufactured to either make or break an electrical circuit at a factory pre-set temperature and reset automatically on cooling. Some devices can be used as controlling thermostats, which cycle open and closed more rapidly to maintain a temperature level. Other devices can be used as over-temperature protectors to limit a temperature from exceeding a predetermined value. Thermtrol offers complete design flexibility for custom probe thermostats. We draw from an extensive inventory of standard components and build the thermostat that is correct for your application.
