The UDS2-73 SWP ultrasonic rail flaw detector is intended for continuous, mechanized rail testing of railway tracks, including turnouts (crossings and frogs), at speeds of up to 5 km/h. The trolley detects defects in both rails along the full length of the track and throughout the rail cross-section, except for the foot flanges. It also enables manual confirmatory testing of specific rail cross-sections and weld joints, determines the parameters of detected defects, and stores all test results in non-volatile memory.
UDS2-73 (Search Wheel Probes)
The flaw detector provides for internal and subsurface defects detecting in accordance with IRS 70712:2018 (UIC 712 R), EN16729-1, EN16729-1, and AREMA.
Design of the flaw detection trolley is compliant with the requirements of EN 13977.
Quantity and type of probes: 11 pcs (00/4MHz, ±37, ±70C, ±70GS, ±70NGS, ↑↓55 SL/2 MHz).
UDS2-73 SWP flaw detector design features
- Ergonomic, light and reliable design of the flaw detection trolley ensures testing of all existing rail sizes of the track (within 950 – 1676 mm).
- Possibility to adjust in three planes the position of the electronic unit for control and visualization (screen) provides for a handy testing in the field. The electronic unit has IP65 rating according to the EN60529 standard.
- Precise positioning on the rails is ensured by the mechanical adjustment of the search wheels (SWP) in the longitudinal and transverse directions, as well as their tilt angle.
- The search wheels (SWP) are galvanically isolated from potential interference caused by the electrical potential of the rails.
Extra options
- To be able to use the flaw detector in the metro, in the tunnels and at nighttime the flaw detector’s chassis is equipped with the front and rear lights for the inter-rail space, illumination scanner-rail contact area, as well as far directional lighting.
- The flaw detector is equipped with a GPS-router to link position of the detected defects to the GPS-coordinates.
- A spare NiMH battery is available upon the customer’s request.
Key features
- Scanning the rail in one pass in one direction.
- Detection of artificial reflectors in the form of flat-bottom holes and cylindrical holes according to EN 16729-1.
- The step of sounding the rail at a testing speed of up to 5 km/h is no more than 1.5 mm.
- Representation of test results in the form of A-scan, multi-A-scan, B-scan for all channels.
- Real-time display of test results in the form of B-scan.
- Data recording and saving (operator’s name, line, direction, track number, initial track coordinate, date, time, final track coordinate).
- Screenshot saving (PrintScreen).
- Saving of test results in the form of data array (B-scan) to the internal memory.
- Use of USB flash drive for transferring the test results to PC.
- Saving track coordinate (Encoder) and global coordinate (GPS).
- Post-viewing of test result on the flaw detector with the possibility to measure conditional sizes of defects.
- Possibility to put the track markers (e.g. “Bridge”, “Crossing”, “Bolt hole”, etc.).
- 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.
- The flaw detector provides detection of internal defects in accordance with the following codes per IRS 70712:2018 (UIC 712 R).
- The “Rail Inspector” program for viewing and analyzing the test results on a PC is included in the flaw detector delivery set.
- The time of continuous operation of the flaw detector from a fully charged battery is at least 12 hours.
- Presence of a screen (LCD) 10'' with high resolution for high-quality display of testing results in the form of B-scan with color amplitude gradation.
- The presence of a sun-protective hood during the monitoring in sunny weather.
- The flaw detector during operation is resistant to the action of the following climatic factors: ambient air temperature from minus 30 to plus 55°C and air humidity 95%.
REPORTS
The user has access to 3 types of quick reports generated from the device menu, as well as 4 analytical reports that are generated on a remote workstation on a computer using special software "RailInspector". Report examples are given in the pictures below.
