Brochure

The ROWA-WT is an ultrasonic phased

array test system for online wall

thickness measurement and lamination

ﬂaw detection in tubes.

The ultrasonic coupling is realized by

a rotating water jacket, generated by

tangentially ﬂowing coupling water

(GE patent). Due to the compact

dimensions of the mechanics, the

ROWA-WT system can be seamlessly

integrated into an existing production line.

The tubes are fed into the test chamber

one by one on linear tracks by means of

a guiding and transport device. A lifting/

shifting table is required for installation

of the test mechanism within the

guiding and transport line.

The field proven and reliable GE ultrasonic electronics processes all signals and carries out a separate evaluation according to flaw type and position. In order to avoid misinterpretation due to electrical interferences, noise suppression takes place by means of dual-threshold method prior to generating the inspection result: No test shot is lost, every single pulse is evaluated.
