Flooding protection tube for
FDU90
L00-FDU90xxx-15-00-00-xx-001
Usage
The flooding protection tube prevents the level to rise into the blocking distance of the FDU90 sensor even if
the sensor is flooded.
The user can set a safety distance SD in the transmitter FMU90/FMU95 and define that a warning signal is
generated as soon as the level rises into the safety distance.
Mounting hints
In order to ensure tightness, the supplied gasket has to be applied and the flooding protection tube must be
screwed hand tight up to limit stop. When re-equipping the flooding protection tube, repeat the basic setup
including the mapping
!
Note!
The flooding protection tube has a G1-1/2" thread.
If it is ordered together with the FDU90 sensor in the product structure, the sensor always has a G1-1/2"
thread at its front side, irrespective of the selection in feature 020, "Process connection".
If the flooding protection tube is ordered as an accessory, it can only be used for sensors with a G1-1/2" thread
at the front side.
