Ultrasonic Flaw Detection - Rail Flaw Detectors - Manual Ultrasonic Rail Scanners - Dual Rail - OKOndt UDS2-73 RSUI Ultrasonic Rail Flaw Detector

The AREMA CODE requires that ultrasonic rail flaw detectors have the capability of detecting VSH (Vertical Split Head) defects. This requires 11 probes/channels. The two additional probe/channels make AREMA compliant models a bit more expensive than 9 probe systems which do not have the capability to detect VSH type flaws. We offer 9 probe systems to those customers that are not concerned with VSH type flaws.

Overview

The UDS2-73 RSUI Ultrasonic Rail Flaw Detector is designed for continuous testing of both rails on the rail track including turnouts (crossings, frogs) at a speed of up to 3.3 mph (5 km/h). The UDS2-73 RSUI benefits from a lower weight, more attractive design, use of 6.3" (160 mm) immersion wheel, easy to use mounting adjustment mechanism, foot brake and many other features. The ergonomic, light and reliable design of the trolley ensures testing of all existing rail sizes and defect detection in both rails of the track along the entire length and rail cross-section (except for rail foot flanges). The UDS2-73 RSUI flaw detector ensures testing in compliance with the requirements of IRS 70712:2018 (UIC 712 R), AREMA, EN 16729-1.

Key Features

Detection of artificial reflectors in the form of flat-bottom holes and cylindrical holes according to EN 16729-1 and internal defects in accordance with the following codes per IRS 70712:2018 (UIC 712 R).
10" high resolution LCD screen for high quality display of B-scan results with color amplitude gradation.
Possibility to adjust in three planes the position of the electronic unit for control and visualization (screen).
Quantity and type of probes: 11 probes per rail (total of 22) 0°/4MHz, (±45, ±50, ±70C, ±70GS, ±70NGS) 37°/ 2 MHz
Mechanical adjustment of the wheel scanners position longwise and transversally, as well as the scanners slope angle provides a possibility to precisely position the immersion wheel on the rail thus to ensure maximum testing scope.
The wheel scanner unit is isolated (galvanic isolation) from interferences which may be caused by electrical potential of the rails.
Display modes: A-Scan, Multi-A-Scan, B-Scan, A-Scan+B-Scan
Real-time display of test results in the form of B-scan with data recording and saving (operator’s name, line, direction, track number, initial track coordinate, date, time, final track coordinate).
Saving of test results in the form of data array (B-scan) to the internal memory or use of USB flash drive for transferring the test results to PC.
Signaling about the presence of defects: sound, light, visual, indication of the set testing sensitivity values, defect coordinates, current track coordinate–digital on the screen built into the flaw detector.
