PBCOver reverse running protection unit
The PBCOver combines three functions in one instrument:
•
Reverse running protection, meaning the sensor can only be
moved in one direction during assembly.
•
Process seal, meaning compressed air cannot escape during
assembly thanks to an enclosed O-ring.
•
Adjustable fixation, so that a precise immersion depth and
alignment is possible (similar to the pressure point on a car
clutch). 360° alignment is possible at any time (rotation of the
sensor).
The PBCOver reverse running protection unit must not
be disassembled (loss of functionality) and can be used
at an overpressure up to 16 bar.
Tapping clamp
The tapping clamp allows the sensor to be installed precisely using
the drill unit without the need for welding. The corresponding supply
line may be under pressure (normal operating conditions) when in-
stalling the tapping clamp or when repairing/replacing the sensor.
Assembly of the tapping clamp under pressure should
only be made by trained personnel, and is permitted for
a maximum pressure of 16 bar (up to DN 200) and 10
bar (DN 250 and DN 300, Assembly under pressure,
page 21).

ping clamps:
