Type of probe installation
• Probes are mounted to the process connection with threaded connections or flanges and are usually also
secured with these. If during this installation there is the danger that the probe end moves so much that it
touches the tank floor or cone at times, the probe must, if necessary, be shortened and fixed down.
The easiest way to fix the rope probes is to screw them to the internal thread on the lower end of the weight
(Thread size, → ä 26).
• The ideal installation is mounting in a screwed joint / screw-in sleeve which is internally flush with the
container ceiling.
• If installation takes place in a nozzle, the nozzle should be 50 to 150 mm in diameter and should not be
more than 150 mm high. Installation adapters are available for other dimensions, → ä 35.

Welding the probe into the vessel
Caution!
Before welding the probe into the vessel, it must be grounded by a low-resistive connection. If this is not
possible, the electronics as well as the HF module must be disconnected. Otherwise the electronics may be
damaged.
Special notes for bulk solids
• In the case of bulk solids, as great a distance as
possible from the filling curtain is especially
important to avoid wear.
• In concrete silos, a large distance (B) should be
observed between the probe and the concrete wall,
if possible ≥ 1 m, but at least 0.5 m.
• The installation of rope probes must be carried out
carefully. The rope should not be buckled.
If possible, installation should be carried out when
the silo is empty.
• Check the probe regularly for defect.
