Resistance thermometers measure temperature of an. object based on changes in electrical resistance of the. sensing element. Two types of resistance thermometers are. commonly used: thermistors and resistance temperature. devices (RTD). A thermistor uses a semiconductor as the sensing. element. The electrical resistance of the semiconductor, made mostly from metallic oxides (e.g., NiO), decreases. sharply as the temperature increases.
