Application

 

WDA-1/WDA-1A can be applied in a variety of complex regions, energy resource and city geophysical exploration, railway and bridge prospecting, metal and non-metal mineral resources prospecting, city geophysical exploration, hydrology and engineering geology to inspect base of dam and flood protection levee for incipient faults. Besides, it contributes to geothermal survey.

 

 

Main Feature

Portability and flexibility: the transmitting unit and the receiving unit are designed in one device, small and lightweight. The 96V internal battery of WDA-1A 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-1A system can ensure accurate measured result even in harsh environment.

 

WDA-1/WDA-1A 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.

 

Multiple functions: voltage and current range and small signal accuracy are

allowed to increase dramatically, which makes it suitable to work with rock

sampling tester, high-power IP receiver, general electrical method instrument, IP instrument, water finder, 2D and 3D multi-electrode electrical method instrument, etc. l Measuring various parameters, wide application: it is able to acquire data of voltage (VP), current (IP), apparent resistivity (R0), Self-Potential (SP), apparent polarizability (M~M7), metal factor (G1~G7), half decay time (TH), deviation (r), induce polarization ratio (J), etc. 

 

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-1A 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 the pocket PC to control the WDA-1/WDA-1A main frame in 10 meters. Sampling control, parameters setting, measurement manipulating, data transferring and displaying, graph plotting can also be

realized through the pocket PC, and thus field work becomes easier.
