Emerson’s WirelessHART® Fisher® position monitor extends safety and performance gains

22 February 2011

The monitor is a linkage-less device that provides accurate feedback from valves previously unconnected to the control system.

Emerson Process Management has expanded its Smart Wireless family with the Fisher® 4320 wireless position monitor. Beyond its wireless advantages, the monitor is a linkage-less device that provides accurate position feedback and uses industry standard WirelessHART® communications.

Most process plants have hundreds, or even thousands, of valves that are not connected to the control system because of high wiring costs. These valves currently provide no feedback on their actual positions, even though incorrectly positioned valves represent a significant cause of safety-related incidents. Unfortunately, users have typically not been able to access the position data that is valuable to the performance and safety of their plant.

The Fisher 4320 wireless position monitor changes the economics since it represents only 10% to 20% of the installed cost of a wired solution. The wireless monitor installs and commissions quickly, providing users with a cost-effective way to access the information.

The Fisher wireless device monitors equipment such as valves, regulators, louvres, displacement and float level sensors, and relief valves in standard and hazardous area locations. With its patented non-contacting rotary and linear monitoring, the 4320 is adaptable to almost anything where a percentage measurement of span is desired.

The Fisher 4320 wireless position monitor is part of Emerson’s broad range of intelligent, digital field devices that power the PlantWeb™ architecture to improve plant efficiency by 2% and more through delivering asset optimisation, process automation, and management execution. Like all other devices in the Emerson Smart Wireless family, the 4320 position monitor offers secure and reliable performance. The position monitor has a 5- to 10- year SmartPower™ battery life and is fully compatible with existing Smart Wireless networks.

Emerson’s Smart Wireless solutions are an extension of the PlantWeb digital plant architecture, combining highly reliable, smart monitoring devices with wireless transmitters in an innovative self-organising mesh network that automatically adapts as device points are added or removed, or obstructions encountered.

The Smart Wireless family offers solutions for field instrumentation and plant operations. The Fisher position monitor is one of the wireless solutions for field instrumentation. The family also includes the TopWorx™ 4310 wireless position monitor, which wirelessly detects rotary or linear movement, and monitors the on/off status of valves and sliding-stem regulators, safety relief valves and more. Other wireless devices include Rosemount® transmitters, Rosemount Analytical and Machinery Health™ Management devices, and native wireless interfaces to AMS Suite predictive maintenance software, DeltaV™ or Ovation™ digital automation systems, and wireless SmartStart™ Services.

Smart Wireless solutions for plant operations use industrial Wi-Fi devices for applications such as connecting disparate field networks, communicating with mobile workers, tracking people and/or mobile assets, and video monitoring.
