  • 21.3 Thermistors and Resistance Temperature Detectors (RTDs)

    One of the simplest classes of temperature sensor is one where temperature effects a change in electrical resistance. With this type of primary sensing element, a simple ohmmeter is able to function as a thermometer, interpreting the resistance as a temperature measurement: Thermistors are devices made of metal oxide which either increase in resistance with increasing…
