11. Technical data
For resistance thermometers, thermocouples or standard signals with 2
nd
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.
