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 and oil & gas production and transmission.
