Measuring nozzle geometry
Take into consideration the necessary measuring nozzle geometry.
Execute the outlet of the nozzle with sharp edges. Angled edges at the outlet opening are not
permissible.
Measuring nozzle configuration
Safeguard air discharge.
In the event of gap distance queries of <30 μm, it may be necessary to reset the outlet openings of
the nozzles by 30 … 60 μm after the bearing surface in order to permit air discharge.
The bearing surface, in which the measuring nozzles are mounted, must be provided with ducts that
permit exhaust to the outside (
è
Fig. 8).
Observe the permissible tube lengths between the sensor module and measuring nozzle
(

Technical Data, Chapter 11).
