Emerson Process Management”s Rosemount 708 Wireless Acoustic Transmitter is designed to help processing plants reduce energy expenses and environmental impact by combining temperature measurement with acoustic “listening” technology to provide visibility into the state of steam traps and pressure-relief valves. Steam production is a significant operating expense for processing plants, and about 20 percent of the steam leaving a boiler is typically lost through failing steam traps, according to Emerson. The Rosemount 708 Wireless Acoustic Transmitter provides accurate measurement and constant visibility to steam traps without the effort of a manual inspection, which Emerson projects will enable decreases in steam-trap failures and fuel cost reductions of 10-20 percent each year. Manual monitoring for releases at pressure-relief valves occurs periodically and does not indicate when or why a release occurred, increasing the chances of a safety, regulatory, or environmental incident, according to Emerson. The Rosemount 708 Wireless Acoustic Transmitter provides visibility to pressure-relief valves by alerting operators when a valve has opened in as little as a second. The time-stamped alerts can be compared against process conditions or environmental reporting to help identify the root cause of a release so that preventive actions can be taken to reduce future emissions. The transmitter gives operators instant visibility to all their critical steam traps and pressure-relief valves through a non-intrusive, WirelessHART monitoring system.
