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.
