Big Hermet – Hermetically Sealed Temperature Switch

SOR’s hermetically sealed Big Hermet is designed to keep harsh conditions out so the chance of corrosion and instrument failure is minimized. 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 and is available with a maximum explosion-proof rating.

• Hermetically sealed snap switches
• Ranges from -60° to 1000°F (-51° to 540°C)
• Set point adjustment with calibrated scale
