Dual Hi-Lo - Hermetically Sealed Temperature Switch




-60° to 1000°F, -51° to 540°C


Unit: INMETRO, SIL; Detector: ATEX, UL/CSA, TestSafe (SAA)

SOR’s hermetically sealed, Dual Hi-Lo temperature detector is ideal for explosion-proof applications and/or those applications that require protection of the detector 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 detector incorporates two separate sensing assemblies and two separate set points with two separate detector 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.
