SOR Mini-Hermet Mechanical Pressure Switch

Mini-Hermet Pressure Switches

Explosion Proof, Hermetically Sealed, Robust and Reliable

Introduction
Mini-Hermet Pressure Switches are robust field-mounted instruments. The pressure sensing assembly is similar to a conventional SOR type. The main difference is that the switching element assembly is hermetically sealed in an explosion proof steel capsule. Switching elements are SPDT or DPDT. See Principle description on page 2.

Application Information
The pressure switches in this series are suitable for a variety of process applications in hazardous locations and hostile environments where stainless steel exterior parts are required and where space is limited. Basic models with standard wetted parts are normally suitable for air, oil, water and non-corrosive process fluids. Adjustable ranges to accommodate lower Set Points, switching elements to handle heavier electrical loads and user preference may require Big Hermet models. High pressure fluid power (hydraulic) applications where high shock pressures and high cycle rates are expected normally require Pivot Seal type pressure switches.
