UDS 2-77Single Rail

Ultrasonic Flaw Detector

Key Features

• Detects defects of various orientation along the running surface and in whole cross-section (except for foot flanges) according to UIC Code 712

• Real time data merge from all channels to the common scale B-Scan

• Real time data representation in single and multi A-Scans and B-Scans

• Continuous data recording (bound to track position and GPS as an option)

• Data flagging (“Bridge”, “Crossing”, “Bolt hole”, “Hole”, “Spin”)

• Special modes for automatic testing of Bolt Joints, Switches and for manual testing.

• Full review and evaluation of recorded data directly in the instrument

• Easy to calibrate

Trolley structure highlights

• Light weighted (only 16 kg ) due to usage of impact-proof plastic

• Parking stand

• Modular structure: frame with rollers, central electronics unit, mux, battery, water tank, couplant flow adjustment, probes units, suspension mechanism probes units, encoder

• All modules are firmly fixed, but easily removed

• Adjustable position of central unit in 3 axes

• Adjustable position of probes units across the rail

• Centering of the Probes Units along of the rail axis by adaptive rollers

• The suspension system of the Probea Units ensures stable acoustic contact at a transverse tilt of the trolley by ±15°
