3.3 Electrolyte/electrolyte vessel

The sensor's reference electrode and measuring electrode are combined in one element. In order to
ensure the functionality of the reference system, a conductive connection between reference system
and medium is required. This connection is produced by electrolyte, which is able to enter through the
diaphragm on one side.
In order to ensure this conductive connection permanently, a permanent electrolyte current
through the diaphragm is required.

3.3.1 Structure of the electrolyte vessel

Fig 6: Structure of the electrolyte vessel
The electrolyte is supplied in a soft infusion bottle
made of PE and introduced into the pressure container
of the electrolyte vessel. When the pressure container is
pressurised with compressed air the PE bottle is com-
pressed and electrolyte is squeezed out through the
needle.
