How to use the anchor detection instrument
Introduce the use of the bolt detection instrument for everyone.
The bolt fullness meter probe has an electric spark emission sensor (which has a wide frequency band, short aftershock, good repeatability, and energy control), which can be sent to the anchor at a frequency 2 times higher than that of the supermagnetic transducer. Longitudinal and transverse waves. These waves travel along the anchor and the wave speed depends on the grouting around the rod or at the end where it is reflected back to the probe.
At this time, the probe acts as a receiver to detect the reflected wave, and the reflected wave is analyzed by a computer. By processing and analyzing the signal, the instrument determines the length of the bolt and the overall condition of the rock and grout. These measurements are displayed on the instrument panel.
The test results are completely displayed on the display, the length of the bolt is marked, the value is quantified, and the defect position is marked.
