VEGA VEGAFLEX 67 (-40…+150°C PFA insulated) 4 … 20 mA_HART four-wire - Manual (Page 14)

Fig. 5: Lateral load
E xtreme vibration caused by the system, e.g. due to agitators or
turbulence in the vessel from inflowing medium, can cause the coax
probe of VEGAFLEX 67 to vibrate in resonance. With coax probes of
more than 1 m (3.281 in) length, you must secure the probe by
fastening a suitable insulated brace or guy directly above the end of
the rod.
I f 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.
I n the gravity weight there is a thread (M12), e.g. for a ring bolt
(
optional) - (article no. 2.27424).
M ake sure that the probe cable is not completely taut. Avoid tensile
loads on the cable.
A void 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.
