The use of wireless technology continues to grow as its benefits in terms of energy saving, cost- effectiveness and reliability become more widely appreciated. Sean Ottewell investigates.
El uso de la tecnología sin cable continúa creciendo de la misma forma que sus beneficios en términos de ahorro de energía, relación coste-rendimiento y la responsabilidad se convierte en algo aceptado más extensamente. Informa Sean Ottewell.
Die Verwendung kabelloser Technologien nimmt immer weiter zu, da ihre Vorteile hinsichtlich Energieersparnis, Kosteneffizienz und Zuverlässigkeit immer mehr anerkannt werden. Sean Ottewell recherchiert.
Benefits of wireless technology secure investment

merson Process Management has launched a wireless acoustic transmitter designed to help oil and gas processing plants save energy and reduce
environmental impact. Te Rosemount 708 wireless acoustic transmitter provides instant and constant visibility to critical steam traps and pressure relief valves through a wireless monitoring system. Te new transmitter is part of
Emerson’s ‘smart energy initiative’ which combines its industrial energy expertise with advanced technologies that enable customers to lower energy costs and reduce emissions.
Acoustic ‘listening’ Te new transmitter helps processing plants to significantly reduce their energy expenses and environmental impact by combining temperature measurement
with acoustic ‘listening’ that provides unparalleled visibility into the state of steam traps and pressure relief valves. Steam production is a significant operating expense for processing plants, and about 20 per cent of the steam leaving a boiler is typically lost through failing steam traps. By providing accurate measurement and constant visibility to steam traps without the effort of a manual inspection, the transmitters enable dramatic decreases in steam trap failures and fuel cost reductions of 10-20 per cent each year (Fig. 1). Pressure relief valves are another critical component of a plant. 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. Te 708 provides visibility to pressure relief valves by alerting operators when a valve has opened in as little as a single second.
Te 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.
Instant visibility Backed by Emerson’s proven experience in Smart Wireless field instrumentation, the new transmitter gives operators instant visibility to all of their critical steam traps and pressure relief valves through a non-intrusive, WirelessHART monitoring system.
