Temperature measurement for the analog output
Via the analog output the measured temperature is output.
The temperature sensor is not wetted. It is used to calculate the extent of the
measuring channel. The sensor is influenced by the ambient temperature. The
temperature value will become sluggish, because it measures the plastic -
Temperature inside the sensor pocket.
