SOR INC Mini-Hermet – Explosion Proof Pressure / Compound Pressure Switch

Process pressure changes act on the diaphragm/piston assembly to actuate and de-actuate a snap-action electrical switching element at discrete process pressures. The pressure-sensing element of the explosion proof Mini-Hermet pressure/compound pressure switch is a force-balanced, piston-actuated assembly sealed by the conventional Static “O” Ring type that SOR pioneered. The switching element assembly is hermetically sealed in a stainless steel capsule with the maximum explosion-proof rating.

The small, compact size of the SOR Mini-Hermet makes it extremely popular in offshore oil and gas fields because it doesn’t require much space on the skids and it is corrosion-resistant.

  • Hermetically sealed snap switches
  • Ranges from 30 in Hg vacuum to 7000 psi
  • Set point adjustment without declassification of hazardous area
  • Worldwide agency approvals

Available distribution:  Ontario

Manufacturer info

At SOR we listen and respond to the needs of oil and gas producers, power generation plants and nuclear facilities. In the vast majority of cases, these industries require specialized products that are engineered to order to handle unique environmental or hazardous challenges. Even if the pressure, level, flow or temperature product you need doesn’t exist or is no longer manufactured, our engineering staff can design a device to solve the problem and our in-house machine shop can build it from scratch.
