Measuring tolerances for resistance thermometers
Tolerance classes
The tolerance classes of the resistance thermometers are defined as follows in accordance with IEC 60751:
Tolerance class
Precision
∆
t
Class B
Basic accuracy
±(0.30 °C +0.0050|t[°C]|)
±1.8x0.30 °F +0.0050x|t[°F]-32|
Class A
Increased accuracy
±(0.15 °C +0.0020|t[°C]|)
±1.8x0.15 °F +0.0020x|t[°F]-32|
Class AA (1/3 B)
High accuracy
±(0.10 °C +0.0017|t[°C]|)
±1.8x0.10 °F +0.0017x|t[°F]-32|
Tolerances
The following tables provide an overview of the validity ranges of these tolerances. When you use a thermometer above the
specified limits, the values of the next lower accuracy class apply.
