Typical application 1: explosion test in steel mesh structure
In mid-October 2016, at the request of a university experimental center, our company sent a staff to Fujian Ningde for the explosion experiment of steel mesh shell structure, testing the site, using the L20-P blasting shock wave monitor produced by our company, measuring TNT Explosion of the explosive in the steel reticulated shell structure, vibration and shock waves of the shell;

Typical application 2: underwater shock wave test
In 2017, a monitoring unit in Fujian monitored the impact of shallow sea reef operations on the sensitive fish in cage fisheries. Using the L20-P blasting shock wave monitor, the underwater sensors were placed on the cage to obtain each explosion. Blasting shock wave data for reef operations to guide blasting construction and provide safety for fishery sensitive fish

Installation and use

Before the blasting field test, the user turns on the power of the instrument after fixing the sensor, and completes the parameter setting through the on-board touch button and display screen to start the acquisition and then leave the scene, and the instrument enters the working state. When the blasting vibration signal is transmitted, the system will automatically record and store the entire dynamic waveform. The tester will use the U disk to take the number or use the computer with the client software to establish communication with the instrument to manage, analyze and report the stored files. Production.

Air Shockwave Installation:

1、Fixed sensor bracket, sensor mounting point 1.2 meters from the ground;

2、The shock wave sensor is fixed by a nut, and the sensor points to the explosion surface;

3、Connect the host and sensor according to the test requirements;

4、Protect the equipment to avoid damage to the monitor due to impact;

Measurement and calibration

After the rigorous measurement by the Beijing Aerospace Measurement and Testing Institute, the air shock wave or water shock wave "test report" is obtained. The data of the L20-P type shock wave detection is accurate and traceable to the national benchmark.
