Main Features

1. High-power mode: As the industry-leading high-power transient electromagnetic instrument for mining, the emission current reaches 20A, and the effective advanced detection distance is ≥150m, which can meet the highest energy efficiency in tunnel and roadway environments.

2. Optimized hardware configuration: The integrated receiving and transmitting host design abandons the traditional high-power transmitter in the industry, reducing the labor intensity of downhole technicians and improving work efficiency; the passive transmitting and receiving coils are integrated into a compact structure, and the system configuration is lightweight, suitable for on-site transportation and convenient use; the high-precision touch screen is more user-friendly and convenient to use; the advanced low-power embedded operating system is more stable to use; the data is intelligently stored, eliminating the need for manual operation and storage.

3. Advanced construction method: using an advanced “8” shaped coil construction method to ensure accurate detection capability;

4. Intelligent internal work system: The equipment is equipped with an intelligent internal work interpretation and a one-key automatic drawing system;

5. 3D imaging display: Supports industry-leading 3D imaging display and analysis technology for detection results;

6. By increasing the transmission power, the secondary field is enhanced, the signal-to-noise ratio is improved, and thus the exploration depth is increased; the signal-to-noise ratio is improved by repeatedly measuring and superimposing the secondary field with multiple pulse excitations and applying multiple coverage technologies in the spatial domain. This can be applied to underground mines and tunnel roofs, floors, and advanced detection, where the work is complex and the noise interference is large.
