ATEM-3 TEM Water Detector

TEM (Transient Electromagnetic Method) is on the basis of conductivity and magneto conductivity difference of the earth’s rock (ore), applying electromagnetic induction theory to send primary pulsed magnetic field to underground by un-earthing loop or earth wire source. During the interval of primary pulsed magnetic field, the coil or earth electrode can be used to observe secondary turbulence field then study the space and time distribution rules of the field as well. It is a kind of time domain electromagnetic method that can be used to prospect the subsurface minerals and solve other geological problems.

Main Function:
1.Wire synchronization suit for complex geological condition;
2.IGBT bridge circuit to get high power, fast power off portable electromagnetic transmitter
3.High resolution receiver with float point magnify and FPGA technology
