13 POLYNOMIALS CALCULATION FOR PT100 AND THERMISTOR

This section will explain how to create your own polynomials to be applied when you are using other PT100
or TH10K components with different specifications.

When selecting the pre-defined PT100 or TH10K in the analog section it uses the pre-defined polynomials
to calculate the output in ˚C.

Kipp & Zonen uses a particular PT100 or TH10K which can be purchased in different classes, behaving
differently to temperature changes.
Therefore it’s vital to create a perfect polynomial for temperature sensors other than those from Kipp &
Zonen to have a correct and reliable output.

Each component has its own behavior.
The next two illustration, Figure 1 and 2, will describe the behavior of a PT100 and TH10K which we use at
Kipp & Zonen and can be located inside most product manuals:
