Rotor Detection System

Rotary valves used in pneumatic conveying applications wear and sometimes fail, which can result in the valve’s rotor vanes coming into contact with the valve body. If metal-to-metal contact occurs, metal fragments can break off and contaminate the product, causing costly shutdowns and product rejections. This new Rotor Detection System (RDS) immediately alerts plant operators that metal-to-metal contact has occurred. It monitors the electrical isolation between the rotor and the valve housing. If a rotor vane touches the valve body - even if only for a split second - a warning is sent to personnel via the plant SCADA system and/or the valve is immediately shut down.
