1. GE Measurement amp Control Krautkramer Testing Machines Full Body Volumetric Inspection Of Round Bars ROWA B Series The ROWA B is an ultrasonic phased array test system for detection of core and longitudinal surface subsurface flaws in round bars 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 B system can be seamlessly integrated into an existing inspection line The bars 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 ROWA B test mechanics GE imagination at work Rotating water jacket Dimension dependent guiding bushes at the inlet and outlet sides keep the water jacket within the test chamber and determine its free diameter Rubber sealings prevent water leakage during test and remove the water from the test object s surface after the test Depending on the application and object diameter 4 18 phased array probes with up to 128 elements each are arranged circumferentially in a chamber For testing a multiple number of neighbouring elements are controlled in parallel and form virtual probes Due to sequential activation of virtual probes along the circum ference the ROWA B achieves 100 co2. s a registered trademark of General Electric Company Other company or product names mentioned in this document may be trademarks or registered trademarks of their respective companies which are not affiliated with GE
3. verage of the rotating sound beam without mechanical probe rotation The system does not contain any moving parts which results in overall robustness and easy maintenance One key advantage of the ROWA B is a short changeover time Within a wide dimension range no mechanical probe adjustment is necessary Probes are adjusted electronically by recalling stored parameters only the guiding bushes and the seals have to be changed according to the diameter of the material under test The field proven and reliable GE ultrasonic electronics processes all signals and carries out a separate evaluation according to flaw type and position System Overview System Electronics Type VPA Windows operating system Max 20 kHz PRF in full parallel operation VME bus controller Parameter storage Automatic sensitivity check adjustment Extensive monitoring functions self test and diagnostic support State of the art PC technology Pre wetting system Water circulation system Guiding and transport device Shifting table Test Specifications AMS 2154 class AA Various end user specific standards Technical Specifications Longitudinal surface subsurface flaw testing Core flaw testing Material dia 10 250 mm 100 coverage Test speed up to 120 m min GEIT 60024EN 04 13 2013 General Electric Company All Rights Reserved Specifications are subject to change without notice GE i
