Product description

3.1

General information

The sensor InPro 6800 with integrated temperature
probe is used for oxygen measurement.
The sensor is sterilizable and autoclavable and com-
patible with CIP (cleaning in place).
InPro 6800 sensors with ISM
and Measure as well as enhanced diagnostics features.
ISM sensors are available with K8S (fully digital) or
VP connector.
3.2

Principle

Here is a short summary of the principle of polaro-
graphic measurement on which this sensor is based
(Clark 1961).
a) The Clark polarographic sensor basically consist
of a working electrode (cathode), a counter/refe-
rence electrode (anode), and an oxygen permeable
membrane which separates the electrodes from the
sample medium.
b) The transmitter supplies a constant polarization
voltage to the cathode, needed to reduce oxygen.
c) The oxygen molecules which migrate through the
permeable membrane are reduced at the cathode.
At the same time, oxidation takes place at the anode
and oxidized anode metal (silver) is liberated as
silver ions into the electrolyte. The electrolyte closes
the electric circuit between anode and cathode (ion
conductivity).
d) The current produced by the reactions described
above is measured by the transmitter and is pro-
portional to the partial pressure of oxygen (pO
the sample medium.
Please refer to Section „10 Theory of the polarographic
sensor" for further information.
