2.3 Measurement Principle and Design
The chlorine sensor is a membrane-covered potentiostatic
3-electrode measuring cell with a specially arranged counter
electrode. The measuring electrode is covered by a membra-
ne and, together with the reference electrode, is located in
an electrolyte chamber which is separated from the sample
water and contains a special electrolyte.
With this patented measuring method, chlorine diffuses
from the sample water through the membrane and triggers
an electrical signal in connection with the electrolyte at the
measuring electrode. This electrical signal is proportional to
the chlorine concentration and is amplified by the sensor
electronics. Due to an integrated temperature compensati-
on, the measuring signal is independent of the temperature
of the sample water.
