ATEM-Ⅳ Transient Electromagnetic System



Main Applications and Features

By adopting the lead synchronization technology, ultra-high power detecting range can be extended from a few meters to a thousand meters; with multiple function in one machine, with integration of superficial part and intermediate part, the instrument is suitable for the place with features like mountainous areas and complicated geological environment; by adopting IGBT bridge circuit, high-power, quick shut-off, portable electromagnetic transmitter can be realized; by adopting floating-point amplification and FPGA technology, high-resolution receiver can be realized; USB port data transfer facilitates the man-machine dialogue, thus the system can be widely used in investigation works including metal mine, coal field, oil field gas, geothermal, water resources survey and including environmental pollution detection, etc.
