The One Series Safety Transmitter pressure or temperature monitoring transmitter switch from United Electric Controls provides a NAMUR NE 43 standard 4-20 mA analog output. Its programmable, high-capacity solid-state relay enables fast emergency shutdowns. Its “I Am Working” sensor diagnostics with redundant data processing detects open, shorted and plugged sensing elements. Its analog output provides process variable and detected-fault information. Discrete outputs provide a fail-safe (open) emergency shutdown when a fault is detected. Setpoint and deadband (reset point) are 100 percent programmable. It is password protected. LED backlighting enhances viewing of process variables, parameters and status in dimly lit areas. 617/926-1000; www.ueonline.com.
