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 29.
• 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 ... 150 mm in diameter and should
not be more than 150 mm high. Installation adapters are available for other dimensions, see
"Accessories" on → ä 77.

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.
