Overview
KOSON KS-205 cracking sounder is a special instrument for cracking depth test of concrete surface.
Features
1. Simple operation: Chinese menu, test immediately after startup, simple button to complete the test.
2. The results are intuitive: no need to measure the wave speed, no need to calculate, directly display the cracking depth.
3. Data processing: Data can be passed into the PC to quickly print the detection data.
Principle
The vibration energy propagates in the concrete, and when it passes through the cracking, the vibration energy diffracts at the cracking endpoint, and the diffraction angle has a geometric relationship with the cracking depth. The cracking sounder realizes the High Accuracy sounding of cracking based on the geometric relationship between the diffraction angle and the depth.
Applications
Concrete surface cracking depth test
Standards
"Technical specification for ultrasonic detection of concrete defects" CECS21:2000
Steps
1. Cross-slit test: measurement L ′ = 0, 5, 10, 15, 20mm... diffraction wave vibration signal.
2. The results show that the cracking depth is directly displayed on site.
