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.
