Influence of the reference
junction
Pt100 DIN IEC 60751 Cl. B (internal reference junction with thermocouples TC)
If an external RTD Pt100 2-wire sensor 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.
Installation
Mounting location
If stable sensors are used, the device can be fitted directly to the sensor. For remote mounting on a
wall or stand pipe, a mounting bracket is available. The illuminated display can be mounted in four
different positions.
