EXPLOSION-PROOF PRESSURE, VACUUM, DIFFERENTIAL PRESSURE AND TEMPERATURE SWITCHES • Meet global requirements with worldwide certifications and approvals • Certified for use in SIL2 functional safety systems. SIL3 capable • NACE MR0175 compliant models • Increase flexibility with multiple outputs • Easy installation via dual electrical conduit openings • Simplify wiring through easy-to-access terminal block • Match process requirements with an assortment of available sensors • Improve measurement accuracy with ultra-low pressure ranges RoHS compliant

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. • Standard product approvals The 120 Series offers a variety of pressure, vacuum, differential pressure and temperature ranges, as well as process connections, wetted materials and sensor...
