Insertion thermometer Model TF43 With plastic moulded measuring element
Measuring element, tolerance
WIKA standardly uses the following measuring elements for the model TF43 insertion thermometer:
NTC, R25 = 10 kΩ ±1 %, B (25/85) = 3977
NTC, R25 = 10 kΩ ±1 %, B (25/85) = 3435
Pt100, class B per DIN EN 60751
Pt1000, class B per DIN EN 60751
Others on request
Platinum elements offer the advantage of meeting international standards (IEC 751 / DIN EN 60751).
Due to material- and production-specific criteria, a standardisation of semiconductor elements, e.g. NTC’s, is not possible. For this reason their interchange ability is limited.
Measuring ranges from -50 ... +105 °C (briefly up to +120 °C)
