tightened into the counterpart.

other accessories.
If the PEEK tip or PEEK sealing rings for sliding connection is
damaged or seriously scratched, the instrument or sealing rings
should be replaced.
The switch has a protection class of IP67 when mounted with a
correct IP67 M12 cable or in cable version. If mounted with a
stainless steel M12 connection the switch conforms IP69K if

The capacity (C) of the media is directly proportional to the dielectric value of the
media
A frequency between 100 and 180MHz is swept into the media
When the coil (L) and the capacitor (C) reach a resonance frequency, it will be
detected by the electrical circuit

When re-ordering a CleverLevel switch
If a new CleverLevel switch is installed in an existing applica-
tion, it is normally a "plug-n'-play" operation.
If the settings of the level switch was changed from standard
factory settings, it is necessary to re-adjust the new switch to
same as the "old" switch. It is possible to save the settings of
the "old" switch on the PC/FlexProgrammer and download those
again to the new level switch.
The factory settings of the sensitivity of the media may vary up
to ±1,5%. This means that if a very exact set point is required, a
new teach-in or adjustment by the FlexProgram must be per-
formed.
