4 Channels Ultrasonic Cross-Hole Pile Testing System
Applications:
It is specially designed to test the pile integrity and DWALL integrity by acoustic-transmission method. This system has 4pcs probes, it can test 6sections in one time. It can be used to test the large diameter piles with more than 4pcs sonic tubes. It can also be used for testing the DWALL defect. With the strong probe signal, the probe can test the space up to 8m between the two sonic tubes.

Features:
1. A hoist can simultaneously accomplish the measurement of six sections, with 4 grades adjusting the hoisting speed. The hoisting speed is up to 60m/min.
2. The transmit-receive radial probe is combined with pre-posed amplification techniques, is perfectly solving such industry complexities as dimness and difficult interpretation of first wave. The size of transducer is small, with 25mm diameter and 20cm length. The measurement span of concrete is up to 8m.
3. Original iteration interpretation can automatically make the accuracy of first wave interpretation up to 99% under complex conditions.
4. The built-in software is proficient and flexible, the interfaces can display in different color to suitable various working environments.
5. The defects can be accurately fixed by means of real-time repetition measurement and cryptographic measurement in the process of measurement.
6. The professional data processing software can rapidly analyze the data, and form a detection report, whose formats can be freely customized.
