Wireless valve monitoring

The solution transmits real-time position indication to the control room and enables predictive maintenance for actuated valves, delivering capital and operating expenditure reduction, increased safety and increased productivity.

RI Wireless products are certified as Zone 1 Intrinsically Safe for use in hazardous areas. By introducing comprehensive plant monitoring, the system enhances operational efficiencies and eliminates unnecessary shutdowns. Predictive maintenance is facilitated through the monitoring of valve opening and closing profiles and the detection of variations from reference profiles.

The system comprises of a small, battery powered Valve Monitoring Device (VMD) that is installed on existing or new valve actuators using a NAMUR interface, or on manual valves with an ISO 5211 interface. The VMD collects dynamics-of-state data from the actuator or valve and transmits it as a 64-point packet, providing the information required for preventative maintenance.
