Product Details
Time-domain TEM Transient Electromagnetics Induced Polarization for Geophysical
Exploration Underwater Detection with GPS
The WTEM Transient Electromagnetic device utilizes lead
synchronization technology to extend its ultra-high power detecting
range from a few meters to a thousand meters. This device offers
multiple functions in one machine, integrating the superficial and
intermediate parts, making it suitable for areas with complex
geological environments like mountainous regions. The adoption of
the IGBT bridge circuit enables the device to achieve high-power,
quick shut-off, and portability in its electromagnetic transmitter.
Additionally, the inclusion of a USB port for data transfer
facilitates seamless communication between the device and the user,
allowing for a wide range of applications in tasks such as metal
mining, coal field exploration, oil and gas surveys, geothermal
studies, water resource assessments, and environmental pollution
detection.

The WTEM Transient Electromagnetic device is utilized in a wide
range of geophysical survey applications. These include searching
for metal and non-metal mines, conducting groundwater exploration,
and detecting hidden hazards such as ant nests and cracks in river
levees. It is also used for urban prospecting, engineering surveys
for railways and bridges, archaeological excavation, and geological
structure mapping. Additionally, the device is employed in
hydrology studies, environmental surveys, resistivity method
engineering surveys, exploration of coal mine goafs, civil air
defense projects, karst caves, and assessing geological disasters
that impact plant foundations, highways, bridges, railways, and
landslides.
