United Electric (UE) Spectra 12 Temperature Switches with Bulb and Capillary System

United Electric 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 prolonged switch life. Its small conical washer transfers motion to a hermetically sealed 1 or 5 amp microswitch. The Belleville spring snaps over when pressure is applied and snaps back on pressure release.

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. A 1 Amp switch is available for use in intrinsically safe circuits. Approved for use in hazardous locations worldwide, the 12 Series is installed within applications ranging from offshore oil rigs to rotating equipment, and more.
