117 Series Overview
Hermetically Sealed Pressure Switches, Vacuum Switches, Differential Pressure
Switches and Temperature Switches
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. 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.
