UE 820E-1BS 822E-1BS UE explosion-proof temperature switch

UE 820E-1BS 822E-1BS  overview

As safety requirements become more stringent, the determining factor in specifying an industrial pressure, differential pressure and/or temperature switch rests upon that switch protecting equipment, processes and personnel. Meeting hazardous location requirements through adherence to UL, CSA, and ATEX standards, UE’s 120 Series is the choice where potentially explosive or highly corrosive atmospheres exist. The 120 Series offers a variety of pressure, differential pressure, vacuum and temperature ranges, as well as port connections, wetted materials and sensor types. With common, flexible “platforms”, models can quickly be adapted at the factory for special requirements, such as ranges, process connections and electrical ratings. Typical industries using 120 Series switches include chemical, petrochemical, refinery, oil and gas pipelines & production and pharmaceuticals. An innovator in the application of Threshold Detection and Switching™ technology since 1931, United Electric’s primary focus is the protection of equipment, processes and people.
