Gometrics - Excela Electronic Process Thermostat/Pressure Switch

SHARE

The ONE Series safety transmitter has been designed by UNITED ELECTRIC CONTROLS to simplify installation, increase safety and eliminate false alarms. Redundant self-diagnosis “IAW” of the equipment detects the open/closed state and faulty sensor. The analog output of the transmitter provides the process variable and fault detected information. It has digital outputs to provide an alarm of equipment failure to execute an emergency stop. The instrument is password-protected to prevent unwanted parameter changes, eliminating the risk of tampering, and memorizes internally the maximum and minimum values reached. The LED backlighting incorporated in the equipment improves the visualization of process variables, parameters and status in low light locations.
