Other installations
• Select the mounting location such that the
distance to internals (5) (e.g. limit switch,
struts) > is 300 mm over the entire length of
the probe, also during operation.
• Probe must within the measuring span not
touch any internals during operation. If
necessary: when using rope probes the probe
end (4) may be fixed to ensure that → ä 29!
Optimization options
• Interference echo suppression: Measurement
can be optimised by electronically tuning out
interference echoes.
Separable probes
If there is little mounting space (distance to the
ceiling), it is advisable to use separable rod pro-
bes (∅16 mm).
• max. probe length 10 m/394 inch
• max. sideways capacity 20 Nm
• probes are separable several times with the
lengths:
– 500 mm/19.68 inch
– 1000 mm/ 39.37 inch
• torque: 15 Nm
Centering of probe end
If the centering disk is mounted at the end of the
probe, it enables a reliable measuring.
See "Ordering structure" → ä 8.
• Centering disk for rod probes:
– d = 45 mm (DN50/2" + DN65/2 1/2")
– d = 75 mm (DN80/3" + DN100/4")
