120 Series Overview

      Rugged, Explosion-proof Pressure, Vacuum, Differential Pressure and 

Temperature Switches

      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 worldwide 

approvals and certifications, UE’s 120 Series is the choice where 

potentially explosive or highly corrosive atmospheres exist. 

     The 120 Series offers a variety of pressure, vacuum, differential pressure 

and temperature ranges, as well as process connections, wetted materials 

and sensor types. With a common flexible platform, 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 production 

and transmission, and pharmaceuticals.
