Reducing length of installation and measuring length (control range)
The measuring tube and the electrode can be cut to suit the individual requirements of the
installation.

215 200
315 300 50
415 400 50
515 500 50

1. Carefully determine the required reduction of length - measured from the bottom end of
the measuring tube - and mark this on the measuring tube.
2. Only slacken locking grub screw using a screwdriver size 1.3 for socket-head cap
screws.
3. Unscrew measuring tube and cut it to the length marked.
4. Unscrew spacer disc.
5. Mark the reduction of length - measured from the extreme end of the tip - on the
electrode tip.
6. Cut electrode tip to length. Cut back 10 - 12 mm of the insulation.
7. Screw back the spacer disc onto the electrode tip and fasten fingertight with a 12 mm
open end spanner.
8. Screw back measuring tube with a torque of 50 Nm and tighten locking grub screw.
Attention
! The seating surfaces and threads on the vessel and mounting flanges must be
accurately machined.
! Do not bend the electrode tip when cutting. Do not subject electrode to physical
shocks.
! Do not lag the electrode body.
! The conductivity transmitter system can be installed horizontally or with a vertical
inclination. The measuring surface must be permanently submerged.
