Wireless transmitters have been applied to a variety of applications. Some examples are monitoring temperatures in cold rooms (photo); monitoring temperatures in mobile situations, such as in railcars; and temperature measurement in harsh plant environments, such as in steel mills. This company recently announced the expansion of its wireless solutions with the release of the Extended Range Antenna, available on Rosemount 3051S, 648, and 702 transmitters with WirelessHART output. Oil and gas industries and others operate facilities where measurement points are separated by long distances, making wiring and powering of measurement points expensive. The extended-range-antenna option provides a cost-effective way to access this information by increasing the distance between self-organizing points up to a half mile (2,600 ft). — Emerson Process Management, Pittsburgh, Pa.
