Fixing rope probe
L00-FMP4xxxx-17-00-00-en-027
• The end of the probe needs to be secured if the
probe would otherwise touch the silo wall, the
cone or another part, or the probe comes closer
than 0.5 m to a concrete wall. This is what the
internal thread in the probe weight is intended for:
– 4 mm rope: M14
– 6 mm rope: M20
• Preferably use the 6 mm rope probe due to the
higher tensile strength when fixing a rope probe
• The fixing must be either reliably grounded or
reliably insulated ("Accessories", → ä 62).
If it is not possible to mount the probe weight with
a safe earthed connection, it can be secured using
an isolated eyelet, which is available as an
accessory (→ ä 68).
• In order to prevent an extremely high tensile load
and the risk of rope crack, the rope has to be slack.
Make the rope longer than the required measuring
range such that there is a sag in the middle of the
rope that is ≥ 1 cm/m of the rope length.
