The Future of Rail Flaw Detection: Better, Faster, Smarter

Dual-track Type Ultrasonic Internal Rail Flaw Detector independently developed by Shenhao Technology has been proven effective at finding on the order of 100% of the internal defects in rail before something catastrophic happens. This NDT equipment allows for continuous inspection of railway track at up to 15km/h (running speed 20km/h).

Railway transportation is one of the most important parts of modern economic development. With the rapid development of modern science and technology, people are also constantly strengthening the performance and safety management construction of railway transport, so as to effectively improve the efficiency and speed of railway transportation. However, the rail, as one of the important elements supporting the railway transportation, under the constant increase of load, aggravates its fatigue and damage in the actual operation.


The traditional hand-push flaw detection trolley has low detection efficiency and can no longer meet the needs of track maintenance. However, the use of large-scale flaw detection vehicles is limited by the number of configurations due to the high price, and it is difficult to carry out work effectively.

The main feature of Shenhao Dual-track Type Ultrasonic Internal Rail Flaw Detector includes:

Wide range of application: Suitable for urban rail, ordinary rail (passenger and freight) and high-speed rail line rails, compatible with 43kg/m ~ 75kg/m rails;

Strong environmental adaptability: It supports operation in harsh climates such as night and rain and snow, supports low temperature operation of -25 degrees, and has a battery life of more than 60km;

Fast detection speed: the maximum detection speed is 15km/h, the maximum running speed is 20km/h, and the disassembly time is less than 5min;

High flaw detection accuracy: the self-adaptive probe frame ensures the height of the track surface, the sampling interval is less than 2mm, the total 18 probes on both sides automatically generate B-scan images, automatically identify and alarm, and have remote data playback and query functions

3D Vision: Ensenso B now also available as a mono version!

3D Vision: Ensenso B now also available as a mono version!

This compact 3D camera series combines a very short working distance, a large field of view and a high depth of field - perfect for bin picking applications. With its ability to capture multiple objects over a large area, it can help robots empty containers more efficiently. Now available from IDS Imaging Development Systems. In the color version of the Ensenso B, the stereo system is equipped with two RGB image sensors. This saves additional sensors and reduces installation space and hardware costs. Now, you can also choose your model to be equipped with two 5 MP mono sensors, achieving impressively high spatial precision. With enhanced sharpness and accuracy, you can tackle applications where absolute precision is essential. The great strength of the Ensenso B lies in the very precise detection of objects at close range. It offers a wide field of view and an impressively high depth of field. This means that the area in which an object is in focus is unusually large. At a distance of 30 centimetres between the camera and the object, the Z-accuracy is approx. 0.1 millimetres. The maximum working distance is 2 meters. This 3D camera series complies with protection class IP65/67 and is ideal for use in industrial environments.
