6.3.7.1 Connection of pH or ORP sensors via a coaxial cable
Fig. 34: Coaxial cable:
1. Protective sleeve
2. Insulation
3. Inner conductor
4. Outer conductor and shielding

There are two connection types:
NOTICE!
Possible incorrect measurement due to poor elec‐
trical contact
Only use this type of connector if you do not wish
to use pre-assembled coaxial cables. Observe the
following with this type of connection:
Remove the black plastic layer from the inner
coaxial cable. There is a black plastic layer on all
types of cable. When doing so, ensure that indi‐
vidual threads of the shielding do not come into
contact with the inner conductor.

The pH or ORP sensors are connected using a
coaxial cable directly via the controller's electrical
terminal. This relates to the pH/ORP via mV con‐
nection type.
There is a connection type without potential equalisation (unsym‐
metrical connection type) or a connection type with potential equal‐
isation (symmetrical connection type).
