Main Features
1. the system can be used in investigation
works including metal mine, coal field, oil field gas, geothermal, water
resources survey and including environmental pollution detection,
2. By using the lead synchronization
technology, ultra-high power detecting range can be extended from a few meters
to a thousand meters;
3. by adopting IGBT bridge circuit,
high-power, quick shut-off, portable electromagnetic transmitter can be
realized;
high-power, quick shut-off, portable electromagnetic transmitter can be
realized;
4. by using floating-point amplification and
FPGA technology, high-resolution receiver can be realized; USB port data
transfer facilitates the man-machine dialogue, etc.
