Installation

3.4.1 Mounting kit
In addition to the tool needed for flange mounting, you will require the following tool:
• 4 mm Allen wrench for turning the housing.
Shortening probes
Rod and rope probes can be easily shortened. This is necessary if the distance to the
container floor or outlet cone is less than 150 mm in the case of a rope probe, or less
than 100 mm in the case of a rod probe or less than 50 mm in the case of a coax probe.
Shortening rod probes
The rods of a rod probe are shortened by sawing or separating at the bottom end.
Shortening rope probes
• Remove ballast weight:
– The weight is fixed to the probe rope
with 3 Allen setscrews (M4, Allen key
AF3). The screws are secured with
Loctite. This may first have to be made
plastic with a hot air apparatus.
• Remove released rope from the weight
• Measure off new rope length
• Wrap adhesive tape around the rope at
the point to be shortened to prevent it
from fanning out.
• Saw off the rope at a right angle or cut it
off with a bolt cutter.
• Insert the rope completely into the
weight,
– thin rope (4 mm) 60 mm deep,
– thick rope(6 mm) 80 mm deep
The weight is then refixed to the rope:
• Reapply screw locking fluid (we recom-
mend Loctite type 243) to the setscrews
and screw into place.
• When doing so, observe the following
torques:
– For 6 mm rope: 15 Nm
– For 4 mm rope: 5 Nm
Shortening coax probes
Coax probes can be shortened max. 80 mm from the end. They have centering units
inside which fix the rod centrally in the pipe. The centerings are held with borders on the
rod. Shortening is possible up to approx. 10 mm below the centering.
