Programmable pressure, differential pressure, and temperature transmitter-switch with safety relay output. Front-panel display and keypad adjustment, I Am Working self-diagnostics, NEMA 4X/IP66 epoxy-coated aluminum alloy 360 enclosure with tempered glass window, SIL-2 certified, SIL-3 capable UL listed, cUL certified, CSA approved, CE compliant.

United Electric's One Series Safety Transmitter was designed to simplify installation, improve productivity, and eliminate nuisance trips. The One Series Safety Transmitter is certified for use in SIL 2 functional safety applications (HFT=0), and is capable of SIL 3 applications when augmented by redundancy and voting logic.

These new combination transmitter/switches feature "I Am Working" sensor diagnostics with redundant data processing detect open, shorted, and plugged sensing elements. Their analog output conforms to the NAMUR NE 43 standard and provides process variable and detected-fault information. Discrete outputs provide a fail-safe (open) emergency shutdown when a fault is detected. Solid state relay setpoint and deadband are programmable over 100% of span. And its programmable high-capacity solid-state safety relay output enables the fastest emergency shutdowns.

  • Pressure ranges: -14.7 to 30 PSIG to 0-6000 PSIG, Differential pressure ranges: 0-5 to 0-200 PSID, Temperature ranges:-40° to 450°, 900° or 1000° F, -300° to 200° F, depending on mounting configuration
  • Type 4X/IP66 polyester-painted aluminum alloy 360 enclosure with UV-resistant pressure sensitive keypad and display faceplate
