GE Krautkramer CHAT - Compact Hollow Axle Tester
The newly developed Compact Hollow Axle Tester CHAT combines the proven HW probes with GE’s high quality USIP 40 ultrasonic instrument. With up to eight probes in one probe holder, in a diameter range from 30 to 90 millimeters, full A-scan data recording, C-scan displays (separate or merged with TOF correction), and two motorized scanning axes, CHAT offers a typical inspection time of 12 to 15 minutes for an entire axle, while the spiral scan pattern guarantees full coverage of the test object.
Pricing available upon request
Features and Benefits
Electronics and mechanics designed to cover the entire diameter range
Rapid adaption to new diameters just by exchanging centering devices (3 parts in total)
Motorized motion (closed control circuits) in linear direction and for probe holder rotation
Signal connection through slip ring to allow continuous rotation of the probe holder and to reduce the inspection time
Quick pluggable cable connections between trolley and inspection mechanics
Light design of inspection mechanics that can be handled “just by one person” with no need for lifting
Closed loop for oil coupling to minimize oil loss during the inspection
Full post-processing possibilities and signal display: A-scan and of
Endless rotation of the probe holder, oil coupling closed loop system, modular push/pull U-profile to inspect the whole axle length just from one side
Speed - Rotation: 35 RPM; Linear: 30mm/s max;
Inspection length - 2,4 m typical with connectable U-profiles, extensions available
Inspection time - 15 min typical, depending on UT setup
Trolley - Moveable trolley carrying PC (notebook equipped with own battery), UT-Instrument, PLC, oil tank with pumps and storage space for inspection mechanics and U-profiles
Weight - Inspection mechanics approx. 10 kg plus trolley approx. 90kg (without Oil, UPS, main power cable)
Electric - 220-240V ~50Hz, 15 m mains cable at trolley
Typical applications in the rail and transportation industries.
