NtcConversion

A converter from the resistance of a semiconductor to temperature.

The NtcConversion processing block can be found in the ‘Templates’ feature in the PMP installer.

In some systems it can be useful to model the resistance of a semiconductor at different temperatures. The NtcConversion processing block allows the conversion from the resistance of a semiconductor to temperature based on the Steinhart-Hart equation.

Description

The implementation of the processing block is shown in Implementation of the NtcConversion processing block.

The elements of the block are directly one-to-one related to the Steinhart-Hart equation, which is given by

\[Temperature = \frac 1{A + B \ln R + C (\ln Resistance)^3}\]

with \(A,B,C\) the Steinhart-Hart coefficients.
