SOR’s hermetically sealed Mini-Hermet temperature switch is your “tight space” alternative to the Big Hermet. It is designed to keep harsh conditions and atmospheres from potentially causing instrument failure. It uses a vapor-pressure thermal system design to sense temperature changes and activates/deactivates a diaphragm/piston assembly. This versatile temperature snap switch works in a wide variety of process media and industrial applications–especially where space is limited.
