The RI Wireless 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.

Rotork RI Wireless is a revolutionary concept for wireless valve monitoring and diagnostics, offering end users significant cost benefits. The field proven solution delivers capital and operating expenditure reduction, increased safety and increased productivity.

Features of the RI Wireless system include:

• No wires, conduits, cable trays or cabinets.
• Accurate position indication with alarm capability, identifying to the control system the exact position of the valve, in percentage of openness (0%-100%) or by exact degree.
• Real-time feedback with 100 milliseconds response time, regardless of the number of devices in the network.
• Simple system scalability; additional sensors installed are auto discovered and become part of the network.
• Self-healing wireless mesh network with dynamic routes enabling flexibility, redundancy and resiliency.
• Diagnostic capabilities for actuated valves in the routine operation.
• Certified Zone 1 Intrinsically Safe for hazardous areas.
• Lightweight sensor (180 gram).
• Full installation, commissioning and site service support
• Complete valve adaption service provided by Rotork Valvekits.

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.

A network of Valve Device Routers (VDR) transfer the monitoring data from the VMDs on a wireless MESH network to the Tunneling VDR (TVDR), which is the ‘last hop’ VDR that transfers the data to the RI Wireless Gateway, an industrial computer that manages the RI Wireless system. Several TVDRs can be connected to the RI Wireless Gateway via Transmission Control Protocol (TCP) or Internet Protocol (IP) networks.

The final element in the structure is the RI Wireless Management System (WMS), a software management tool that provides operational and maintenance data in common industrial standard connections to an HMI, DCS or PLC.

The system is programmed and commissioned using a hand-held Operator Device (OD) instrument that provides oneto- one wireless communication with the VMDs. In addition to supporting installation and configuration, the primary functions of the OD are turning devices on and off and receiving real-time feedback regarding the status of individual VMDs.
