120 Series Pressure and Temperature Switch

• SIL 2 certified (SIL 3 capable) switch providing reliable local switching of final element in safety instrumented systems (SIS)
• Simplified installation with ample access to wiring compartment, terminal block, and set point adjustment
• Protect piping and vessels with heat trace/freeze protection temperature models
• Application versatility achieved through a variety of ranges, microswitches, sensors and process connections

Explosion-proof SPDT/DPDT and multi-switch output for control and safety applications

Heavy industrial processes rely on 120 Series pressure and temperature switches to protect equipment and personnel while preserving process uptime. The 120 Series is simple to install in hazardous location areas and perform critical alarm, safety and emergency shutdown functions. As an electromechanical switch, it can safely operate independently of the control system and switch reliably when needed, free from potential communication errors or cyber concerns.
Typical applications that utilize the 120 Series include rotating equipment such as pumps, turbines, and compressors, heat tracing, combustion systems, and oil, gas and chemical processing.
