RTDs happen to be those special types of temperature sensors, which are primarily utilised for the principle of electrical resistance for the purpose of measuring temperature. These tend to consist of a wire made from a material whose resistance changes predictably with temperature. RTDs tend to offer high accuracy as well as high stability over a wide temperature range, making them popular in industries where precise temperature control happens to be quite crucial. So, these are sensors that make use of the change in electrical resistance with temperature so as to provide highly accurate & quite stable temperature measurements in a wide rangeof applications.
