Functional Principle, Technical Data
Demodulator module DL6228
The demodulator module DL6228 consists of an internal preamplifier, demodulator, output stage and A/D
converter. The internal preamplifier generates the distance dependent measuring signal and amplifies it. De-
modulator and output stage convert the measuring signal in a standardized voltage and current signal. The
measuring values can be processed digitally with the help of the A/D converter.
The trim potentiometer zero allows a special zero adjustment of the analog output
