5. Installation of sensor
To obtain optimum results from the measuring system, the chassis body of the sensor must have
the same electrical potential as the liquid being measured.
Electrically
conductive
piping
A: Potential equalization with electri-
cally conductive graphite gaskets
Electrically
non-conductive
piping
C: Potential equalization with electri-
cally conductive graphite gaskets
Graphite gaskets
The sensor must be installed between two adap-
ters. Potential equalization with the liquid oc-
curs automatically via these adapters and
through the adjacent pipe.
Potential equalization is carried out with the
built-in grounding electrodes. No further actions
need to be taken.
Please note: MAG 3100 has no grounding
electrodes if the electrodes materials are
platinium or tantalum or PN 100.
EPDM or PTFE gaskets
B: Potential equalization using earth
strap supplied.
D: Potential equalization using sepa-
rate potential equalization ring
