3 RTD temperature probe
3.4 Tolerance classes
Change in tolerance depending on the measurement temperature (thin film)
Tolerance classes – temperature validity range (from DIN EN 60751)
t = measurement temperature in °C
± tolerance/K
Measurement temperature/°C
1/3 Class B Class A Class B Class 0.5
Tolerance class Sensor category Temperature range Tolerance
