Approved for Division 2, Zone 2 hazardous and corrosiveatmospheres, and with optional Zone 0 intrinsic safetycompliance, the 117 Series can be used to measure vacuum,pressure, differential pressure, or temperature in a varietyof applications. The rugged, one piece enclosure features aslanted cover for wiring accessibility to the enclosed terminalblock that is wired to either a SPDT or DPDT hermeticallysealed microswitch. All welded, stainless steel pressureconnections and sensors provide superior corrosion resistance NACE compliant and fire-safe protection within theharshest environments. The 117 Series is an ideal choicefor the most demanding applications; typically steel andaluminum mills, chemical and petrochemical plants, pulpand paper mills, wastewater treatment plants, midstream anddownstream oil & gas, and pharmaceutical plants.Class 1 Division 2 safety switch comes in vacuum, differential pressure, and temperature modelsOptional ATEX or EAC intrinsic safety compliance for Zone 0-65 to 160F (-54 to 71C)Set point repeats after 2.5 G, 5-500 HzSet point repeats after 15 G, 10 millisecond duration
