Influence of the reference
junction
Pt100 DIN IEC 60751 Cl. B (internal reference junction with thermocouples TC)
If an external 2-wire RTD is used for the reference junction measurement, the measured
error caused by the transmitter is < 0.5 °C (0.9 °F). The measured error of the sensor
element also needs to be added.
13.5 Environment
