Fast growth seen for infrared thermometers, thin-wire RTDs
Infrared thermometers and thin-wire resistance temperature detectors (RTDs) will grow faster than all other temperature sensors in the U.S., with average increases of 11.8% and 11.5% respectively through 2004, according to a new report by Flow Research and Ducker Worldwide (Bloomfield Hills, Mich.
Infrared thermometers and thin-wire resistance temperature detectors (RTDs) will grow faster than all other temperature sensors in the U.S., with average increases of 11.8% and 11.5% respectively through 2004, according to a new report by Flow Research and Ducker Worldwide (Bloomfield Hills, Mich.).
"The Market for Temperature Sensors and Transmitters in the Americas" includes within sensors, thermocouples, RTDs, thermistors, infrared thermometers, and thermowells. The total market for these temperature sensors in the U.S., Canada, and Latin America was $540 million in 1999.
The study found that thermocouples are still the most widely used type of temperature sensor, though RTDs have been making inroads in this market. Within the RTD field, growth in thin-film RTDs is outpacing growth of wirewound RTDs due to improved thin-film technology and lower prices. Similarly, increasing education is fueling wider use of infrared technology and products. These are used when contact thermometers aren't practical, such as in motion, high temperature, and remote spot checking applications. Use of infrared thermometers for determining temperatures at a distance is expected to become more widespread as users become more familiar with them.
In addition, the study also found that shipments of high-tier temperature transmitters are expected to increase at an average annual rate of 9.6% over the next five years. High-tier temperature transmitters, more accurate than smart transmitters, often accept more than one type of sensor input. These include FOUNDATION fieldbus and Profibus temperature transmitters. Meanwhile, shipments of analog transmitters are projected to decline.
