Transient Electromagnetic Magnetic Survey Instruments


Transient electromagnetic magnetic survey instrument is mainly used for exploration of metal mines, coal fields, oil and gas fields, geothermal, hydrologic engineering geology, etc.


Features:


One instrument with multiple functions: this system is integrated with functions of a transmitter and a receiver, portable and simple in connection. WTEM-3Q has function of deep exploration with an external high-power TEM transmitterin cable synchronization or mode GPS synchronization mode.

High reliability, low power consumption: refined receiver and circuitry, reasonable heat dissipating system design, sealed and rugged mechanical structure, ensuring high reliability, low power consumption and convenient operation.

Remote control: Tablet PC based Bluetooth wireless communication technology enables it to control the receiver in 10 meters, such as setting parameters, starting measuring, transferring and displaying the measured results.

High anti-interference performance: program controls the filter to give accurate power supply frequency; besides, data stacking and software filtration also do good to this performance.

Flexible power supply mode: the power supply waveform with standard duty cycle (1:1) and the power supply waveform with user-defined power supply pulse width, optional, so that the instrument has a wider exploration application. width

Adjustable number of time windows: operator could set number of time windows, linear or logarithmic; crystal oscillator accomplishes timing, with stable and precise time–to-depth ratio. Sampling window arrangement is reasonable, imaging the true subsurface structure. It provides references to complex geological problems.

Multiple working mode: single-point and continuous working mode,optional.

Wide depth range prospecting: this system is equipped with high-power transmitter which could easily inspect the objects deep in meters to hundreds of meters (for shallow exploration)
