Make sure that the probe cable is only hand tight. Avoid strong tensile
loads on the cable.
Keep in mind that measurement is only possible up to the tensioning
component. For this reason, order the cable probe 270 mm longer.
L = L1 + 270 mm (10.63 in)
ø < 8 mm
(ø < 0.315")

L1 Max. measuring length
Probe length L = L1 + 270 mm (10.63 in)
In case of difficult installation conditions, the probe can also be
mounted laterally. For this, adapt the rod with rod extensions or
angled segments.
To compensate for the resulting changes in signal runtime, let the
instrument determine the probe length automatically.
The determined probe length can deviate from the actual probe
length when using curved or angled segments.
If internal installations such as struts, ladders, etc. are present on the
vessel wall, the measuring probe should be mounted at least 300 mm
(11.81 in) away from the vessel wall.
You can find further information in the supplementary instructions of
the rod extension.
In case of difficult installation conditions, for example in a socket, the
probe can be suitably adapted with a rod extension.
To compensate for the resulting changes in signal runtime, let the
instrument determine the probe length automatically.
You can find further information in the supplementary instructions of
the rod and cable components.
