  • KTY11-6
  • KTY81-210
    Others on request

    Dual measuring element
  • 2 x Pt100, class B per DIN EN 60751
  • 2 x Pt1000, class B per DIN EN 60751
  • 2 x Ni1000, DIN 43760
    Others on request

    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.
