     Platinum elements offer the advantage of meeting international standards （IEC 751 / DIN EN 60751）.Nickel elements are also standardised, but not international.
Due to material- and production-specific criteria, an standardisation of semiconductor elements, e.g. NTC's and KTY, 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 accuracy and linearity.
     High accuracy and linearity are also possible with NTC's, but only in a limited temperature range.
