4.3 Shortening the coax probe
Thenumbersrefertotheguresonthefollowingpages.
Caution:
Sharp edges are created when the probe is shortened. Please wear
work gloves when handling the parts.
Use your personal protective equipment (e.g. safety glasses, hearing
protection, etc.) when using power tools.
1. Dismount the sensor.
2. Determine the new sensor length (L) with a measuring tape and
mark cutting line with a marker.
If possible, position the cutting line on a part of the tube without

3. Use a vice with tube or prism jaws.
Clamp the tube (7) of the probe in the vice.
The later cutting position should be close to the vice.
4. Place the tube cutter (4) on the marked position from below and
tightenrmly.
With stainless steel tubes, the tube cutter (4) can easily slip out
of position. For that reason tighten the tension screw of the tube
cutter (4) at each turn and repeatedly check that it is still in the
correct position.
Continue with this procedure until the tube is completely cut
through.
5. Plug the saw guide sleeve (3) onto the rod (8) of the probe and
slide it (3) into the tube (7) of the probe.
To make it easier to insert the saw guide sleeve (3), you can press
the rod (8) of the probe to the centre of the tube with a screw-
driver.

thesawguidesleeve(3)andsawotherod(8)oftheprobe.
Towards the end, saw very carefully so that the saw guide sleeve
(3) does not get damaged.
7. Pull the saw guide sleeve (3) out of the tube (7) of the probe.
8. Apply the conical hand deburrer (5) to the rod (8) of the probe
and debur the rod tip.

10. Remove the metal chips from the inside of the tube (7) of the
probe.
For better cleaning, you can also blow out the chips with com-
pressed air.
11. Insert one of the retaining rings (1) into the mounting tool (6).
Make sure that the gripping claws of the retaining ring point
towards the mounting tool, so that retaining ring can be slid on.
