Min. off time: 1.2µs (only resistant load) Synchronization model: wire synchronization Dimensions: 360*250*250 mm Weight: 9Kg Receiver Dimensions: 324*210*230 mm Weight: 7Kg (batteries not included) Sampling frequency: max. 5µs, optional. Dynamic range: 156dB Stacking fold 1 to 9999, optional Belt-width: DC in 30KHz Synchronization model: wire synchronization TEM (Transient Electromagnetic Method) is on the basis of conductivity and magneto conductivity difference of the earths 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.
