Mounting

Moisture

Moisture from outside
To avoid moisture ingress, the connection
cable to the housing should be looped down-
ward (directly in front of the cable entry), so
that rain and condensation water can drain
off. This is mainly valid for outdoor mounting,
in areas where moisture is expected (e.g. by
cleaning processes) or on cooled or heated
vessels.

Buildup
Generally, buildup on the cable causes dis-
tortion of the measured value. If strong
buildup on the cable is expected, the use of
insulated cable is recommended. The higher
surface quality reduces buildup.

Measuring range
Keep in mind that the cable cannot be used
for measurement all the way to its uppermost
point of connection. A measurement over the
length of the gravity weight or the cable loop
is also not possible.

Cable electrode in solids

Straining
Generally, the measuring result is only slightly
influenced when the gravity weight is in con-
tact with the vessel wall.
Depending on the kind of solid, the installa-
tion or the method of filling, the cable can
"float“ despite the gravity weight. The solid
can push the cable to the vessel wall or to the
top, and incorrect measured values are re-
sult. In this case, fasten the cable securely.
When straining the cable, strong cable forces
should be avoided. In our price list you will
find a spring (accessory) that helps prevent
overloading of the cable.
