Technical Specifications

1. Introduction to FD-GT-20 Digital Rail Ultrasonic Flaw Detector

FD-GT-20 rail flaw detector is the third generation of HUATEC Group all-digital products with TFT color display and lightweight trolley used for railway system. In accordance with TB/T 2340-2012 UT Rail Tester standard issued by Ministry of Railway(China), this equipment is capable of the detection job for rails ranging 43~75kg/m in type. It efficiently spots various flaws at head, web and flange of a rail, applicable to railway, high-speed railway and subway.

The instrument adopts ultrasonic host + operation terminal mode and connects via wireless WIFI. While improving the customer's operation experience, the instrument's Internet plus function can be expanded to realize variety of functions such as human-machine detection separation, data online, offline real-time storage, GPS positioning, data cloud storage, etc. And you can customize your own ultrasonic operation terminal according to the customer's own needs.

Appendix 1. Features and Features

1. The host appearanceis compact, sturdy and light, and the assembly and disassembly are simple. Good environmental adaptability, working environment temperature -15 °C ~ 45 °C, continuous working time is not less than 8 hours, anti-vibration and anti-interference, protection grade IP65.
2. The host has multiple flaw detection channels (multiple probes can be connected at different angles), and the sequential time-sharing cycle works.
3. The 0, 37 and 70 degree probes are designed to fully detect the main parts of the rail.
4. The host structure is in the form of "server + client". "Server" , the host (without input and display), is a 1- N channel ultrasound module; "client" is the operation terminal (input and display), host and client (operation terminal) through the wired network LAN (or wireless WIFI) connection for network communication.
5. Negative square wave pulse excitation mode transmitting circuit
6. The analog filter increases the host signal to noise ratio.
7. The channel gain is a combination of “basic gain” + “compensation gain”.
8. The detection range, material sound velocity, and pulse shift are automatically set according to the selected rail type.
