The Rotor Interference Detection system (RID) detects unwanted contact between the rotor, housing or end covers and alerts operators to potential contamination of the transported product. Integrate the RID into your system for alerts on product buildup or metal contact. In addition to analog outputs, the third generation RID also offers EtherNet/IP™ or 4-20mA output communication, expanding your network's automation capabilities. DMN-WESTINGHOUSE rotary valves are manufactured to the strictest tolerances, making rotor movement unlikely. However, movement can occur when the rotor is damaged by foreign objects passing through the rotary valve. In that case, the robust and simple design of the RID ensures trouble-free operation.
