The 117 Series is approved as a Class 1 Division 2 safety switch (Zone 2) for hazardous atmospheres. It has optional Zone 0 intrinsic safety compliance and can be used to measure vacuum, pressure, differential pressure, or temperature in a variety of applications. The rugged, one-piece enclosure features a slanted cover for wiring accessibility to the enclosed terminal block that is wired to either a SPDT or DPDT hermetically sealed microswitch. The 117 Series Class 1 Division 2 safety switch has welded, stainless steel pressure connections and sensors to provide superior corrosion resistance – NACE compliant – and fire-safe protection within the harshest environments.

Overview

The 117 Series Class 1 Division 2 safety switch comes in vacuum, differential pressure, and temperature models. It is an ideal choice for the most demanding applications; typically steel and aluminum mills, chemical and petrochemical plants, pulp and paper mills, wastewater treatment plants, midstream and downstream oil and gas, and pharmaceutical plants.
