Temperature Switches

Barksdale's range of temperature switches are suitable for gas, liquid and ambient applications. Barksdale was the first manufacturer to offer effective ambient compensation in electromechanical temperature switches revolutionizing temperature switch accuracy through extreme temperature changes.

In a liquid-filled bulb and capillary system, ambient temperature changes affect the expansion of the fluid resulting in “false” temperature sensing. An extreme ambient change from -55°C to + 75°C will decrease the accuracy of most temperature switches by 20% or more. Or, if the temperature changes only 70°, accuracy can be decreased by 15%.

IECEx approved temperature switches are also available for hazardous areas.
