Approved for Division 2, Zone 2 hazardous and corrosive atmospheres, and with optional Zone 0 intrinsic safety compliance, the 117 Series can be used to measure vacuum, pressure, differential pressure, or temperature in a variety of applications.

Type H117K - One SPDT output; epoxy coated enclosure; internal adjustment with “High-Low” reference scale

Buna N diaphragm and sealing diaphragms with epoxy coated aluminum 1/8” NPT (female) pressure connections.

  • Differential Pressure parameters

This combination does not exist.

United Electric Controls
Pressure switches, temperature switches, thermocouples, RTDs, pressure and temperature transmitters, gas detection

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. All welded, stainless steel pressure connections and sensors provide superior corrosion resistance – NACE compliant – and fire-safe protection within the harshest environments.

The 117 Series 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 & gas, and pharmaceutical plants.
