Hermetically Sealed Temperature Switches

      SOR hermetically sealed temperature switches are your choice for applications that are susceptible to harsh process environments and where disrupted functionality could cause a catastrophic outcome. The snap switch is protected in a sealed housing from salt air, hydrogen sulfide and other corrosive agents and atmospheres that might cause contact deterioration and switch failure.

      Big Hermet – Hermetically Sealed Temperature Switch

      Big Hermet – Hermetically Sealed Temperature Switch

      Models: Big Hermet
      Ranges: -50° to 1000°F, -45° to 540°C
      Certifications: Unit: INMETRO, RTN, SIL; Snap Switch: TestSafe (SAA), UL/CSA
      Warranty: 3 Years

      The SOR 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 maximum explosion proof rating.

      • Hermetically sealed snap switches
      • Ranges from -50° to 1000°F, -45° to 540°C
      • Set point adjustment with calibrated scale
      • Set point adjustment without declassification of hazardous area

      Dual Hi-Lo – Hermetically Sealed Temperature Switch

      Dual Hi-Lo – Hermetically Sealed Temperature Switch

      Models: V2
      Ranges: -50° to 1000°F, -45° to 540°C
      Certifications: Unit: INMETRO, RTN, SIL; Switch: ATEX, UL/CSA, TestSafe (SAA)
      Warranty: 3 Years

      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
