→ High precision clock source and digital signal synthesis technology ensure accurate transmission signal frequency.

→ Comes with calibration signal generator, consistency calibration on different instruments and channels can be done at anytime and anywhere.

→ Controller is strictly isolated from the strong electric system to ensure operator's safety.

→ Controller with full Chinese menu, easy to learn and operate

 

Power supply cabinet

Power supply cabinet is mainly used to complete the power's rectification, boost, pressure regulating and signal invert. Power supply cabinet can also be optional with 30,100,200kW.

Advantages:

→ Set boost, regulator and inverter in one.

→ Using current synchronous measurement technology, reduce the system's loss and complexity without steady flow.

→ High  transmission efficiency, equipped with signal controller, multi frequiency transmissiono can be completed at one time.

→ With perfect overcurrent and overvoltage protection function.

→  Can choose any three-phase generator inside China.

 

Receiving system

JSGY-2 wide-area electromagnetic receiver is mainly used to complete the 8 electric field signal acquisition and data processing.

Advantages:

Multiple frequency measurements can be done at one time, with high efficiency.

8 independent 24-bit high-speed AD and a number of 32-bit fast processor make different channel signals achieve the synchronization of high-precision collection.

Full reinforcement, high-performance military notebook is used, with features of touch screen, 360-degree rotation, highlight and so on.

Connector is durable, and easy to plug.

Strong military safety box provides effective three anti-security for the instrument (black and yellow optional).

Receiver power supply mode: dedicated battery box, 12V car battery and 220V electric supply optional.

With lots of Built-in filtering technologies, can effectively suppress the interference of power and harmonics.

Filter and manage the data withh unique algorithm, suppress the random interference effectively.

Real-time display of time-domain waveform and frequency domain data.

With FFT spectrum analysis function, can directly analyze the scene interference.

Instrument comes with powerful data processing and processing functions.

Exploration of Oil and Gas Fields

Tuha basin oil and gas resources widely electromagnetic exploration

Volcanic type reservoir is bred within carboniferous strata depression basin, regardless of position and shape, apparent resistivity interface of Rock-Permian-Triassic system divided by wide-area electromagnetic method is close to interface of seismic reflection. It is shown that wide area electromagnetic method can determine oil and gas structure and supplement earthquake insufficient in area where seismic effect is poor.
