United Electric Controls 100 Series Pressure and Temperature Switches

Versatile, NEMA 4X, SPDT/DPDT switch

The 100 Series is simple to install and operate for alarm, safety and emergency shutdown applications where preserving process uptime, and protecting personnel and equipment are paramount. A rugged switch, the 100 Series is ideal for both heavy industry and the OEM, and carries global agency certification. As an electromechanical switch, it can safely operate independently of the control system and switch reliably when called upon, free from potential communication errors or cyber concerns.

Typical applications that utilize the 100 Series include controlling rotating equipment - pumps, turbines, and compressors, heat tracing, fire suppression systems, and fuel/gas trains.

Features
  • SIL 2 certified (SIL 3 capable) switch providing reliable local switching of final elements in safety instrumented systems (SIS)
  • Quick and easy installation with ample access to wiring compartment and simple set point adjustment using reference dial or scale, and calibrated gauge
  • Application versatility achieved through a variety of ranges, microswitches, sensors and process connections
  • Protect piping and vessels with heat trace/freeze protection temperature models
