Wireless Is On a Roll in the Temperature Measurement and Control Market

Share Print Related RSS

Manufacturers must increase efficiency and productivity to compete, and increasing automation is one way to meet these objectives. The temperature measurement and control market also is seeing the effects of these drivers.

The worldwide market for temperature transmitters may grow at a compounded annual rate of 6.5% over the next five years, according to an ARC Advisory Group study. “Sales of smart temperature transmitters will outpace those of conventional and low-cost devices as users seek to improve their visibility into plant operations to maximize productivity and the availability of production resources,” adds ARC’s Allen Avery.

And much of this boom will be in wireless. “While still in its early stages, the adoption of wireless field devices will dramatically affect the dynamics of the market for temperature transmitters and other field devices. The recent release of the WirelessHART standard will have a significant impact on the temperature transmitter market in the years to come,” adds ARC’s study, “Temperature Transmitter Worldwide Outlook.”

Lara Kauchak, director of Rosemount Temperature, a business unit of Emerson Process Management, explains, “Approximately 80% of the temperature points in an average plant are used for monitoring applications, making them a natural fit for wireless communication.”

Charles Larson, director of technology at Moore Industries-International, adds, “The popular choice will be instruments that measure multiple inputs and communicate over standard industrial buses such as Foundation fieldbus, Profibus, HART and Ethernet.”
