introduction£º


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 ?/SPAN>platforms?/SPAN>, 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.

  • 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?/SPAN>s 120 Series is the choice where potentially explosive or highly corrosive atmospheres exist.
