As safety requirements become more stringent, the determining factor in specifying an industrial pressure, differential pressure, and/or temperature SIL2-certified 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 SIL2-certified switch 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 the 120 Series SIL-certified switch include chemical, petrochemical, refinery, oil and gas production and transmission, and pharmaceuticals.

At the heart of the 12 Series is a Belleville spring assembly. The spring is a small conical washer that transfers motion to a hermetically sealed 1 or 5 amp microswitch. Its ‘snap-action’ provides fast, positive contact transfer. The Belleville spring ‘snaps over’ when pressure is applied and ‘snaps back’ upon pressure release.
