DSHM-8 Transient Electromagnetic Prospector

 

 

Function:

1. TEM (Transient Electromagnetic Method) bases on 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.

2. In 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 Applications:

 

1. Middle and deep resource prospecting, the prospecting depth ranges from 50m~1300;

2. Detect various metal ores, underground water, underground electrical delaminating, underground water filling caves locating, steep angle geological formation prospecting, coal bed and coal goaf area and water-filling area detection.

3. Search geothermal resources, oil-gas field census and exploration in high-resistance covering area (like carbonate rock, igneous rock and frozen soil covering area), etc.

 

Main Advantages:

1. Full metal stainless steel waterproof and dustproof keyboards are more adapted to the moisture and dusty condition, they are more sensitive and can protect equipment better then the using life can be longer.

2. High density project plastic box integrates receiver, signal amplifier and power supply system into one machine, then decreases its volume and weight then it is easy to carry and construct.

3. As the intelligent upgrade version of ATEM-6 deep EM prospector, its functions are much more strong.

4. Industrial IPC as process panel and Windows PE as operation panel, intelligent and user-friendly.

5. LBD as LED display with backlight source, which has the characteristics like no noise, high light and low power consumption, then improves field data acquiring quality.

6. Reach signal acquiring in one button by the method of dynamic floating amplification, then makes the operation simple and convenient, also reduces data instability caused by human factors.

7. Shortcut Smart one-touch makes field work easy and relaxed.
