MT AMT CSAMT Geophysical Magnetotelluric Survey Equipment for Underground Metal and Oil Exploration
The geophysical magnetotelluric system is founded on matureThe technology used includes electromagnetic sounding theory, random signal processing, embedded real-time operating system, large-scale field programmable array logic, high-precision high-speed A/D recording, and other electronics.An all-in-one broadband magnetotellurometer is created by integrating high-frequency magnetotellurics (HMT) and audio-frequency magnetotellurics (AMT), magnetism (AMT), and magnetotellurics (BMT and MT). it is capable of mapping mineral systems up to 50 km deep, imaging deep structural controls down to 2000 m, and providing drill planning solutions for surface exploration.
Feature
Mixing modes of natural and artificial sources: Utilizes both natural (MT, AMT) and artificial (CSAMT, IP, TEM) electromagnetic sources, along with micromotion monitoring and seismic data recording.
Observable tensors and scalars: Enables measurements of both tensor (2D and 3D geological features) and scalar (quick censuses) quantities.
Portable on-site real-time imaging: Utilizes embedded real-time operating system and parallel hardware processing for full-band acquisition of optical and electromagnetic field spectrums. Enables real-time computation of resistivity and phase profiles.
Efficient real-time parallel collection: Supports multiple sampling rates (24kHz, 2400Hz extraction recording, 150Hz, 15Hz continuous recording) for efficient and continuous electromagnetic observation.
