The SOR 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.
- Ranges from -50° to 1000°F
- 316 SS temperature sensing bulbs
- Remote sensing bulb is optional
- Minimal ambient temperature influence
- AC or DC electrical service
