Levelflex M FMP41C with HART/4...20 mA Installation

3.3.5 Notes on special installation situations
Installation at an angle
• For mechanical reasons, the probe should be
installed as vertically as possible.
• Installation with a deviation up to approx. 5°
from the vertical axis is permitted for probes
up to approx. 1 m in length.

Fixing rope probe
• 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:
– for 4 mm rope: M 14
– for 6 mm rope: M 20
• 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 (see "Accessories" on
→ ä 64)! 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 (see
→ ä 64).
• 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 ≥ 1cm/m
(1"/100") of the rope length.
