Mini-Hermet - Hermetically Sealed Differential Pressure Switch




3 to 500 psid


Snap Switch: ATEX, TestSafe (SAA), UL/CSA, UKCA, IECEx

Versatile in a variety of locations where space is limited and a stainless steel enclosure is required to protect against moisture and/or corrosive damage, the hermetically sealed Mini-Hermet differential pressure switch is the product of choice. The sensing assembly of this differential pressure switch is based on the conventional Static “O” Ring type that SOR pioneered in the industry more than 5 decades ago. The switching element assembly is hermetically sealed in a stainless steel capsule and a maximum explosion-proof rating is standard.

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.
