RTD’s are temperature measuring sensors which use the resistance /temperature relationship of material to measure the temperature of a body. RTDs have higher accuracy and stability as compared to Thermocouples usually in the below 600 °C range. Resistance temperature sensors are composed of realizing material generally Copper, Nickel, or platinum, which shows resistance at a specific temperature. If we want to measure temperature with high accuracy, an RTD is an ideal solution, as it has good linear characteristics over a wide range of temperatures.
