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

4.USB port data transmission is easy for human and device communication; supply
a kind of portable electromagnetic system fit for complex geological conditions
for geophysical prospecting and engineering detection.

Application:

Water prospecting, engineering
exploration, water reconnaissance and environment pollution monitoring etc.
