Based on IEC 60751:2008 we can define 4 different classes for resistance temperature detectors. Below you can find an overview of the different classes in sequence based on accuracy:
Class 1/10 DIN B
Class 1/10 DIN B Pt100 sensors have a resistance of 100 ohms at 0°C with a tolerance of ±0.03 °C.
Class 1/3 DIN B
Class 1/3 DIN B Pt100 sensors have a resistance of 100 ohms at 0°C with a tolerance of ±0.80 °C.
Class A
Class A Pt100 sensors have a resistance of 100 ohms at 0°C with a tolerance of ±0.15 °C
Class B
Class B Pt100 sensors have a resistance of 100 ohms at 0°C with a tolerance of ±0.30 °C
In the below chart you can find accuracy levels based on class for thin films.
