Standard temperature range, Pt 100
In the following table you will find the representation of the digitized measured
value for the standard temperature range of the Pt 100 sensor. The characteristic
linearization applies to the following temperature ranges: – 200 C to + 850 C (in
increments of 0.5 C).
