Position Monitor Uses WirelessHART Communications

Emerson Process Management recently announced the expansion of its Smart Wireless solutions family with the release of the Fisher 4320 wireless position monitor. Beyond its wireless advantages, the 4320 monitor is the first and only linkage-less device to provide accurate position feedback. The 4320 monitor 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, louvers, 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 percent of span is desired.

The 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 optimization, process automation, and management execution. Like other devices in the Emerson Smart Wireless family, the 4320 position monitor has 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.
