Advantages and disadvantages of the different measuring elements
The platinum elements Pt100 and Pt1000 offer the advantage of meeting international standards (IEC 751 / DIN EN 60 751). Due to material- and production-specific criteria, a standardisation of semiconductor elements such as NTC is not possible. For this reason their interchange ability is limited. Further advantages of platinum elements are: better long-term stability and better behaviour over temperature cycles, a wider temperature range as well as a high measurement accuracy and linearity. High measurement accuracy and linearity are also possible with an NTC, but only in a very limited temperature range. While Pt100 and Pt1000 in thin-film technology are suitable for temperatures up to 500°C, the standard NTC can be used for temperatures up to approx. 150°C.
