Confectioning variations single-/double- tubing insulation// metal-/ ceramic sheath // screw-in housing // carrier body // Zwischenschieber single-/double- tubing insulation// metal-/ ceramic sheath // screw-in housing // carrier body // Zwischenschieber
Characteristic curve RT = RN [1+A (ϑ-ϑN) + B (ϑ-ϑN)²] RT = RN [1+A (ϑ-ϑN) + B (ϑ-ϑN)²]

RN = nominal resistance
ϑN = nominal temperature (25°C)
ϑN = temperature in [°C]
A, B = constants // A = 7,635 10-3 / B = 1,731 10-5
