WebUnderstanding RTD's. An RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time. An RTD is a passive device. WebA bimetal thermometer always consists of two different metal strips that have a different thermal expansion coefficient. The two strips are joined together inseparably and thus form the bimetal strip. When the temperature changes, the different metals expand to different degrees, which leads to a mechanical deformation of the bimetal strip.
