System Host

Bidirectional Cascade Controller

The bidirectional cascade controller is used in two-dimensional or three-dimensional high-density electrical measurement, which is equivalent to a repeater and converter, and is mainly used to switch electrodes.

The controller is divided into two ends, the end marked with “HOST” is the head end, and the end marked with “END” is the tail end.

Large cable

Each large cable consists of 10 cables, and the cables are connected by cascade controllers.

The large cable has a spacing of 5 meters and 10 meters, and the spacing can also be customized according to customer needs。

Both ends of the cable are male, non-directional, and both ends need to be connected to a bidirectional intelligent cascade controller when in use.

The overall injection molding process is adopted, and the waterproof performance can adapt to various Simple structure, no electrical parts, high reliability and low replacement cost

Case study

The relatively obvious magnetic anomaly section in the survey line is basically consistent with the abnormal range of apparent resistivity and apparent amplitude frequency in the induced polarization. The two verify each other. Combined with the results of the measurement of the physical properties of the main rocks (ores) in the study area, it is speculated that the anomaly is a mineral-induced anomaly caused by magnetite-bearing skarn or iron (zinc) ore body.

The results of high-precision magnetic profile measurements show that there is a relatively obvious magnetic anomaly area near the entire profile. Although the overall magnetic anomaly value is small and the magnetic anomaly range is narrow, the anomaly morphology is regular and the curve is approximately equiaxial. Therefore, it is preliminarily speculated that there is a certain degree of magnetite mineralization in this area.
