Ceramic Wire Wound Platinum RTD Elements

Check up to five results to perform an action.

  • -200 to +600 C
  • 100 ohm DIN RTD
  • Class A & 1/10 th DIN stocked
  • Cryogenic applications

    Our PK series ceramic wire wound elements are used primarily in applications above 500C or below minus 50C where thin film elements cannot be used. They are also used when accuracies as high as 1/10th DIN are required. Because of their larger size they have lower self-heating coefficients which can improve accuracy especially with older instrumentation which may have higher measuring currents.
    Ceramic wire wound elements were once the standard RTD element. They have now been largely replaced for moderate temperatures and accuracy requirements by less expensive thin film and SMD element types. We stock both class A and 1/10th DIN ceramic wire wound elements for applications requiring this design.
