The centric roller guides have two advantages:
The centric triple roller guides have two advantages:
In set-up mode, a calibration piece with reference flaws can be held cen-
trically outside the test line and the test electronics can be adjusted sim-
ply, since the rotating probes periodically scan the test flaw and display
the signal quasi-statically.
For setting of clearance compensation there is no need to hold the cali-
bration piece centrically.
In testing mode, the roller guides improve centricity, especially for smaller
dimensions, and damp vibrations. They are always required if the drivers
for material transport cannot be set up directly in front of and behind the
sensor system.
