Magnetotellurics MT Audio Magnetotelluric Method Geophysical Survey Equipment for Metal detector

 

 

 

Brief of production

   Magnetotellurics (MT) is a natural source electromagnetic method. Its basic principle is to use naturally existing electromagnetic field signals as field sources to detect the electrical structure of underground media. Since the earth itself is a huge magnetic dipole source, naturally existing electromagnetic field signals can be used as field sources to detect the resistivity structure of underground media by observing the distribution characteristics of electromagnetic field signals of different frequencies on the surface.


    The UltraEM Z5 magnetotelluric system is equipped with GNSS satellite synchronization technology with an accuracy of more than 30 nanoseconds. Even in the case of GNSS signal interruption, the temperature-controlled high-precision clock module inside the system can continue to maintain synchronization. The system supports a variety of magnetotelluric measurement techniques, and can use high-frequency magnetotelluric sounding technology (100kHz-10Hz) to explore geological structures from a few meters shallow to a thousand meters deep. This depth range is usually the most active area of ​​human activities. In addition, it can also use audio magnetotelluric sounding (10kHz-0.1Hz), long-period magnetotelluric sounding (1kHz-100000s) or broadband magnetotelluric sounding (10kHz-10000s) to study deeper macro-geological problems. The scalability of the system has been further enhanced. It can not only integrate other electromagnetic methods such as CSAMT, TEM, IP, but also perform conventional seismic recording, including observations of refraction, reflection, micro-motion monitoring and other methods, and support research work on emerging geophysical methods.

 

 

Technical Specification

1. High-sensitivity sensors: Magnetotellurics are equipped with highly sensitive magnetic and electric field sensors to accurately capture subtle changes in the earth's electromagnetic field.
2. Broadband measurement: It can measure electromagnetic field signals in a wide frequency range from low frequency to high frequency, so that geological structures at different depths can be detected.
3. Data acquisition and processing: The instrument usually contains a data acquisition system and is equipped with advanced data processing software to record, store and analyze measurement data and extract underground structure information.
4. Portable design: Magnetotellurics are often designed to be portable, which is convenient for use in various complex terrains and environments.
5. Real-time monitoring and long-term observation: The instrument can be used for both short-term exploration projects and long-term geological monitoring.
6. Anti-interference ability: It has good anti-interference ability and can work stably in complex electromagnetic environments.
