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.

Caution!
If there is a risk of electrostatic discharge from the product, then both processconnection and rope
must be earthed before the probe is lowered into the silo.
Levelflex can be screwed into a threaded socket or flange. Proceed as follows:
Insert probe
• Uncoil rope and lower it slowly and carefully
into the silo.
• Do not kink the rope.
• Avoid any backlash, since this mightdamage
the probe or the silo fittings.

Note!
For flange mounting: if a seal is used, be sure to
use unpainted metal bolts toensure good
electrical contact betweenprobe flange and
process flange.
