4.7 Installing the clamp fixture

Depending on the operating conditions, the antenna ring may be excited to vi
brate. This effect is dependent on
• the speed
• the antenna diameter (depends in turn on the measuring range)
• the design of the machine base
To avoid vibrations, a clamp fixture is enclosed with the torque flange enabling
the antenna ring to be supported.
Installation sequence
1. Loosen and remove the upper antenna ring screw fitting.
2. Fasten the clamp fixture with the enclosed screw fitting as shown in
Fig. 4.7. It is essential to use the new fan−type lock washers.
3. Clamp a suitable support element (we recommend a threaded rod ∅ 3 mm
... 6 mm) between the upper and lower parts of the clamp fixture and
tighten the clamping screws.
