As safety requirements become more stringent, the determiningfactor in specifying an industrial pressure, differential pressure and/or temperature switch rests upon that switch protecting equipment,processes and personnel. Meeting hazardous location requirementsthrough worldwide approvals and certifications, UEs 120 Series is thechoice where potentially explosive or highly corrosive atmospheresexist.The 120 Series offers a variety of pressure, vacuum, differentialpressure and temperature ranges, as well as process connections,wetted materials and sensor types. With a common flexible platform,model scan quickly be adapted at the factory for special requirements,such as ranges, process connections and electrical ratings. Typicalindustries using 120 Series switches include chemical, petrochemical,refinery and oil & gas production and transmissionExplosion Proof Pressure, Vacuum, Differential pressure and Temperature SwitchesCertified for use in SIL2 functional safety systems.
