VEGA VEGAFLEX 66 (-110…+400°C) Profibus PA - Manual (Page 16)

Fig. 5: Lateral load
Excessive system vibration or shocks, e.g. caused by agitators
or turbulence in the vessel (e.g. from fluidisation) can cause
the coax probe of VEGAFLEX 66 to vibrate in resonance.
Should a coax probe of more than 1 m (3.281 in) length should
be used, you can provide a suitable support or guy directly
above the end of the probe to stabilise it.
If there is a danger of the probe touching the vessel wall during
operation due to product movements or agitators etc., the
measuring probe should be securely fixed.
In the gravity weight there is a thread (M12), e.g. for a ring bolt
(article no. 2.27424).
Make sure that the probe cable is not completely taut. Avoid
tensile loads on the cable.
Avoid undefined cable-vessel connections, i.e. the connection
must be either grounded reliably or isolated reliably. Any
deviation from this requirement can lead to measurement
errors.
VEGAFLEX 66 should be integrated in the vessel installation.
This prevents the electronics from strong heating by heat
radiation.
