Prevention of axial stator oscillation
Depending on the operating conditions, the stator may be
induced to oscillate. This effect is dependent on:
S the rotational speed,
S the antenna diameter (depends in turn on the measur
ing range),
S the design of the machine base.
Important
To prevent this axial oscillation, the antenna ring requires
additional support by the customer. There is a socket
(with an M5 internal thread) on the upper antenna seg
ment, which can be used for a suitable clamping device
(see Fig. 5.6). If this is the case, the cable plug also
needs some support, as shown in the construction exam
ple in Fig. 5.7.
