This video tutorial defines and describes the calibration of sensors. This is illustrated using a Resistive Temperature Detector (RTD) and a temperature calibrator. Two calibration models for the RTD are used, Callendar Van Dusen and IEC Coefficients. In addition to calibration, the video also describes and derives several sensor characteristics which include response time, sensitivity, linearity and accuracy.
