Product Details
Geophysical Magnetotelluric Survey Equipment MT AMT Ultra-Broadband
Systems Metals and Oil Detection Device
The geophysical magnetotelluric system is built upon
matureElectromagnetic sounding theory, random signal processing, an
embedded real-time operating system, large-scale field programmable
array logic, high-precision, high-speed A/D recording, and other
devices were employed.An all-in-one broadband magnetotellurometer
is built by combining high-frequency magnetotellurics (HMT),
audio-frequency magnetotellurics (AMT), magnetism (AMT), and
magnetotellurics (BMT and MT). It can map mineral systems up to 50
kilometres deep, image deep structural controls down to 2000
metres, and provide drill planning solutions for surface
exploration.
MAIN 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.
