1 Product description
Scope of delivery
Collimator - optional
The mounting bracket KV 31 contains all necessary parts for fastening
a radiation-based measuring system to tubes with a diameter of
50 … 100 mm (1.97 … 3.94 in).
The two halves of the mounting bracket are already premounted.
Check the completeness of the mounting backet according to the
assembly drawings of chapter "Mounting".
A collimator can be mounted on the sensor side, the source holder
side or on both sides of the mounting bracket.
A collimator directs the radiation directly to the sensor and absorbs the
undirected scattered radiation.

bracket, sensor side
Take note of the following mounting instructions:
l Mount the bracket first, then the sensor and the source holder
l The marking arrow on the console (source holder side) and the
transport lug of the source holder must point in the same direction
after mounting.
l Make sure that the two clamps (5 and 8) of the bracket are in
parallel. Do this by measuring the lateral distances between the
clamps
l To avoid injuries, shorten the threaded rods of the brackets to the
suitable length after mounting
This half of the mounting bracket is already premounted when being
shipped.
When retrofitting a collimator etc., mount the sensor side of the
mounting bracket according to the following assembly drawing.
To facilitate mounting, mount the bracket first, then the sensor and the
source holder.

2 Mounting
When retrofitting a collimator etc., mount the sensor side of the
mounting bracket according to the following assembly drawing.
To facilitate mounting, mount the bracket first, then the sensor and the
source holder.
Note:
Mount the components in such a way that the marking arrows of the
console (3) and the collimator (1) point in the same direction.
Note the following illustrations.

Note marking arrows
The marking arrows on the console and the collimator must point in the
same direction. After mounting, the transport lug of the source holder
must point in the same direction.

direction.

2 Console - Source holder side (VEGASOURCE)
Adjust mounting bracket
Note:
Adjust both sides of the mounting bracket to the respective tube
diameter before mounting the mounting bracket to the tube. This
facilitates the adjustment.
A later adjustment is difficult due to the weight of the mounting bracket.
1 Loosen the four screw connections until the console can be
shifted.
2 Adjust the consoles on the sensor side and the source holder side
according to your tube diameter.
Take note of the marking lines on the bracket. The edge of the
console must be exactly on the corresponding marking line.

Installation of the
Mount the bracket according to the following assembly drawing:
mounting bracket
Tip:
The mounting bracket is very heavy. We recommend using a support,
eg of wood, as a mounting aid to hold the mounting bracket at the
proper height during installation.
1 Before mounting, check if the adjustment with respect to the tube
diameter is correct on both sides of the mounting bracket and if the
marking arrows of the console and the collimator (optional) point in
the same direction.
2 Make sure that the two clamps (5 and 8) of the bracket are in
parallel. Do this by measuring the lateral distances between the
clamps.
3 Tighten the nuts of the threaded rod evenly. Keep the tube
diameter and the stability of the tube material in mind. Avoid
deformation of the tube through an overtightening of the mounting
bracket.

2 Mounting
If you have the impression that the tube cannot permanently carry
the weight of the mounting bracket, sensor and source container,
mount a suitable support below the mounting bracket.
4 Shorten the threaded rods after mounting to avoid injuries.

Mount the sensor and
source holder
Once the mounting bracket is installed, you can mount the sensor and
the source holder.
You can find the torque in the "Technical data".
Danger:
When mounting, make sure that the source holder is reliably switched
off.
1 First of all fasten the sensor.
2 Mount the source holder. Use a suitable lifting device and note the
respective safety regulations for lifting loads.
