The practical accuracy of an rtd will depend on the tolerance of the rtd, the measurement temperature, the accuracy of the mating instrument, and the effects of the interconnecting lead wire. However, there are no perfect temperature. Learn more about the accuracy of temperature measurement using rtds (resistance temperature detectors)

This video explains the international standard iec 60751, which defines three.
Rtd accuracy classes for pt100 and pt1000 sensors
Compare iec 60751 class aa, class a, and class b tolerances and when to specify each rtd element class. Discover how rtd accuracy is influenced by temperature, wire length, and construction Learn to optimize rtd performance for precise temperature. This application note focuses on resistance temperature detectors (rtd), and explains the design essentials to optimize the measurement accuracy
Resistance temperature sensors (rtds) are more accurate and have a higher measurement resolution than, for example, thermoelectric sensors (thermocouples)
