What is an RTD sensor? Resistance temperature detectors, or RTDs, are a class of sensors that change resistance when the temperature of the medium they are inserted into changes. This change of resistance is proportional to temperature and varies in a somewhat linear fashion with temperature. This means that as the temperature increases, the resistance of the RTD also increases. So, if I can measure the RTD’s resistance, I can determine the temperature.
