Dual Hi-Lo – Hermetically Sealed Temperature Switch

SOR’s hermetically sealed, Dual Hi-Lo temperature switch is ideal for explosion-proof applications and/or those applications that require protection of the switch contacts. It operates on a vapor-pressure thermal system and a sensing bulb that activates/deactivates a piston diaphragm according to the process temperature.

The hermetically sealed Dual Hi-Lo switch incorporates two separate sensing assemblies and two separate set points with two separate switch outputs for settings at minimum and maximum temperatures.

It is field adjustable, making it a convenient choice for just about any industry application in a non-hazardous situation.
