WebSensitivity: The voltage drop across an RTD provides a much larger output than a thermocouple. Linearity: Platinum and copper RTDs produce a more linear response than thermocouples or thermistors. RTD non-linearities can be corrected through proper design of resistive bridge networks. WebThe RTD is a more linear device than the thermocouple, but it still requires curve-fitting. The Callendar-Van Dusen equation has been used for years to approximate the RTD curve: Where: R T = Resistance at Temperature T R o = Resistance at T = 0ºC α = Temperature coefficient at T = 0ºC ( (typically +0.00392Ω/Ω/ºC))

WebThermocouples (TCs) and resistance temperature detectors (RTDs) are the most widely used temperature sensors in automation and process control. They are found embedded in motors, valves, turbines, bearings, and a host of other devices. WebApr 1, 2009 · All temperature sensors should be calibrated periodically to verify their continuing performance, but RTDs generally lend themselves to longer calibration intervals and less frequent replacement due to drift.
