A new research study by Flow Research finds several important shifts occurring in the temperature sensor market. The study, "The Market for Temperature Sensors in the Americas," 2nd Edition, says one important technology change is a transition from contact to noncontact temperature measurement. This involves a shift away from thermocouples, RTDs, and thermistors (all contact sensors) to IR thermometers and fiber-optic temperature sensors (both noncontact). In addition, there is a broader shift away from thermocouples, which typically are less accurate and less stable than RTDs and thermistors. (www.sensorsmag.com/1006/SCtemp~)
