Compact harsh environment pressure, differential pressure, and temperature switches. Diaphragm, piston, immersion stem, bulb and capillary sensors with hermetically sealed microswitch, single or dual SPDT switch outputs, NEMA4X, 7, and 9 enclosures for Class I/II, Div 1, Div 2 hazardous environments. UL, cUL, ATEX, and IECEx approvals, CE compliant.
United Electric Spectra 12 series hazardous location switches are ideal for operation in tough applications where space is at a premium. A Belleville spring assembly provides vibration resistance and prolongs switch life. The 316 stainless steel enclosure and hermetically sealed switch provide rugged protection from the environment. The easily accessible adjustment wheel allows in-line field settings. 5-Amp switches are standard, but 1-Amp switch is available for use in intrinsically safe circuits.
- SPDT or DPDT hermetically sealed switch output (SPDT only on temperature switches)
- Stainless steel construction and wetted parts, construction varies by model
- Pressure ranges 8 to 6000 PSI; Differential pressure ranges 0.7" WCD to 150 PSID; Temperature ranges -130° to 650°F
- Snap-action Belleville spring for vibration resistance and stability
- Mounting bracket for retrofit applications
- 1/2" or 1/4" NPTF process connections
- Approved for use in Class I Div 1 and 2, Class II Div 1 and 2, Class III, and Class I Zone 1 environments
