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.
