UT20 Flaw Detection System

UT20 is used to detect rail damage by Ultrasonic nondestructive flaw detection. Based on the existing mature flaw detection vehicle flaw detection system,it can adapt to the bad environment.The speet could reach 20km/h.

Magnetic alignment is adopted in the flaw detection system to ensure that the whole flaw detection module is in the correct position above the rail.

There is only a protective film and water coupling liquid between the ultrasonic sensor and the rail.

This design allows ultrasonic waves to reach rail surfaces more quickly,so that the sensor could get the multiple ultrasonic echoes, increase the accuracy of flaw detection

The flaw detection system adopts modular design with low maintenance cost. In normal use, only the protective film is fragile and consumable, and the overall maintenance cost of the flaw detection system is less than half of the existing detection wheel type.
