Installation

3.4.1 Mounting kit
In addition to the tool needed for flange mounting, you will require the following tool:
• For the mounting of threaded connection: 60 mm Open-end spanner for 1½", 50 mm Open-end
spanner for ¾".
• 4 mm Allen wrench for turning the housing.
3.4.2 Shortening probes
Rod probe
The shortening is necessary if the distance to the container floor or outlet cone is less than 50 mm.
The rods of a rod probe are shortened by sawing or separating at the bottom end.
Rope probes
The shortening is necessary if the distance to the
container floor or outlet cone is less than 150
mm.
• 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 recommend
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
Coax probes
The shortening is necessary if the distance to the container floor or outlet cone is less than 10 mm.
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.
