order digital
filter (configurable).
In 2-wire or 3-wire circuit:
Type Measured value range
Pt100, Pt1000 -200...+850 °C
Ni100, Ni1000 DIN 43760 -60...+250 °C
Ni1000 from Landis & Staefa -50...+160 °C
Line resistance
: < 30
Ω
Line compensation
Not required for a 3-wire circuit.
When using a resistance thermometer in a 2-wire circuit, line compensation can only be
made by means of the offset correction.
Type Measured value range
Fe-CuNi «J» -200...+1000 °C
NiCr-Ni «K» -200...+1372 °C
