3.2.6.2 Dust Protector for FLSE100-PR
The optionally available dust protector PR can be used if dust contamination on the trans-
ducer surface of the single-probe version FLSE100-PR raises a problem. This option is de-
signed to prevent possible contamination of dust on the ultrasonic transducers.
It contains the components ‘‘Dust Protector Right” and ‘‘Dust Protector Left”. The compo-
nents are to be mounted to the upstream sides of the transducers according to Fig. 3.17.

3.2.7 Emergency Air Supply
To prevent damage to the transducers caused by purge-air failure with the devices
FLOWSIC100 PM, PH and PH-S, an optional emergence air supply is availabe. Precondition
for the use of this module is the provision of oil- and dustfree compressed air by the
customer.
Detailed information is available on a special leaflet supplied on request.
3.2.8 Solid-Bourne-Noise Damping-Set K100 Option
If the sender/receiver unit is not acoustically decoupled from the flange, sound energy co-
ming from the plant or through the ultrasonic transducers can affect the transducers and
generate interference signals.
The optional solid-bourne noise damping set K100 can be used to improve the acoustic de-
coupling. It consists of additional gaskets, spring washers and washers as well as appropri-
ate longer securing bolts, which are used for the assembly of the sender/receiver units to
decouple them acoustically. They must be assembled according to the special leaflet sup-
plied with the shipment.
The dust protector is mounted to
the securing bolts of the transdu-
cer carrier.
