chemical current flow, the sacrificial anode is destroyed, thus protect-
ing the ballast tanks against corrosion.
When installed sensors have a conductive connection to the tank, this
current flow protects the sensor also against corrosion. The sensor is
therefore integrated int he protective function of the sacrificial anode.

Connect the sensor conductively to the vessel wall. Avoid insulating
measures such as e.g. insulating tape or rubber rings.
To protect against electromagnetic influences, we recommend con-
necting the cable screen to the inner ground terminals of VEGABOX
02.
Through the installation itself the sensor is already conductively
connected to the vessel wall. Avoid insulating measures such as e.g.
insulating tape or seals.
To protect against electromagnetic influences, we recommend con-
necting the cable screen to the inner ground terminals of VEGABOX
