2D IP Geophysical Exploration Instrument for Metal Prospecting

Applications

The 2D IP Geophysical Exploration Instrumetn can be widely used in the exploration of metal and non -metal mineral resource exploration, urban material exploration, and railway bridge exploration. It is also used to find hydrological and engineering geological explorations such as groundwater, determining the base of reservoir dams, and hidden dykes in flood control.

Features

• Portability and flexibility: the transmitting unit and the receiving unit are designed in one device, small and lightweight. The 200V internal battery of WDA-1B mainframe can conduct multi-electrode imaging in wide variety of environments.

• Unique and open measuring process control. User-defined power-on time and power-off time controls measuring process. The main frame can also monitor variation of electrode potential automatically. If the parameter exceeds the user-defined over-variation limit, it stops measuring, and wait to measure again until it becomes stable. Thanks to this function, WDA-1/WDA-1B system can ensure accurate measured result even in harsh environment.

• High power supply, wide current range, high accuracy: maximum power reaches 7200W (1200V×6A), voltage input is 64Vp-p, small signal measurement precision is high (voltage is less than 0.1mV and current is less than 0.1mA with ±1% measurement precision), both of which make WDA-1/WDA-1B main frame an ideal device for regions of high resistivity and to achieve better measured results.

• Bluetooth technology facilitating wireless remote control: Bluetooth technology enables pocket PC to control the WDA-1/WDA-1B main frame in 10 meters; sampling control, parameters setting, measurement manipulating, data transferring and displaying, graph plotting can also be fulfilled over the pocket PC, and thus field work becomes easier.

• Extendable easily: data sampling and storing are controlled by pocket PC. Data management is easy. Software is flexible to be upgraded and extended.

• WDA-1/WDA-1B is designed with two cable sockets which enable cross-hole electrode array configuration works without switching control unit, and thus makes the measuring process much simpler and easier.

• Excellent anti-interface performance: integrated with multistage filtration and signal enhancement technologies and suppresser against common mode interference and differential mode interference. Measurement precision is high.

• Pocket PC controlled and powerful function: English version pocket PC to control sampling and relevant parameters setting, data displaying and storing, graph plotting for 10 kinds of electrode array configurations (such as, 4P-VES Schlumberger, 4P-VES Wenner, Combined electric sounding, four-pole electric profiling, Combined electric profiling, Rectangle/Middle Gradient, dipole-dipole, Five-pole Longitudinal Axis Electrical Sounding, Quadratic time difference array, etc). Moreover, advance hardware enables operator to have agenda and to connect with Internet wirelessly, with software such as WORD, EXCEL, PowerPoint, Media Player and so on.

• Receiving unit supports transient over-voltage protection for input voltage; transmitting unit supports over-voltage protection, over-current protection and AB open-circuit protection as well as DC high voltage reverse connection protection.

• Earth resistance check: earth resistance of AB Current electrodes and MN Potential electrode can be inspected at any time.

• Diagnosis program can find the fault or failure quickly and accurately.

• Sealed constitution features waterproof and dust-proof design, long lifetime.

Flexible option of control: control unit may also be notebook PC to remotely manipulate measurement.
