Overview implemented RTD transformations
Some Beckhoff IO devices (IP20 terminals, plug-in modules, box‑modules) support the evaluation of resistance sensors for temperature measurement (RTD) as Pt100, Pt1000, NTC1K etc.
The following are the characteristic curves partially implemented there depending on the device. The table values given are the basis for the evaluation in the device.
- Pt, Ni, KTY: the table values are stored in the device accordingly; intermediate values are interpolated. For KL terminals the temperature is calculated deviating from this via an approximation polynomial.
- NTC: the table values were used for determination of the Steinhart-Hart coefficients and by these coefficients the terminal determines the temperature.
