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.

 

APPLICATION FIELD
