25 August 2006 - A new research study published by Flow Research finds several important shifts occurring in the temperature sensor market.
The study, called "The Market for Temperature Sensors in the Americas, 2nd Edition"' says that the temperature sensor market in the Americas totalled $62m in 2005. It estimates that revenues from sales of temperature sensors in the Americas will increase at a compound annual growth rate (CAGR) of 4.2 per cent through 2010, when they are expected to reach $760m. One important technology change is the shift away from contact temperature measurement to non-contact measurement. This involves a shift away from thermocouples, RTDs, and thermistors to infrared thermometers and fibre-optic temperature sensors. Infrared thermometers are a form of non-contact temperature measurement, while fibre-optic temperature sensors have both contact and non-contact varieties. In addition to the shift towards non-contact temperature sensors, there is a broader shift away from thermocouples. Thermocouples typically are less accurate and stable than RTDs and thermistors. End-users who wish to achieve greater accuracy and stability in their temperature measurements can either switch to a different type of contact temperature sensor, such as an RTD or thermistor, or can go to a different technology altogether such as infrared or fibre optic. Some temperature measurements, such as the temperature of moving objects, cannot be made by contact methods. Even so, thermocouples do maintain some advantages in high temperature environments, and they are still the most widely used method of temperature measurement in industrial markets.
According to Dr. Jesse Yoder, president of Flow Research, other changes are occurring as well. "It is interesting to compare the temperature market today to the temperature market of 2000. Some changes that were going on then are still occurring now, like the shift from wirewound to thin-film RTDs. But other changes are occurring, like the development of fibre-optic temperature sensors and the further development of infrared thermometers. In addition, a great deal of consolidation has occurred in this market."
