Dual Frequency Induced Polarization Instrument
The Dual Frequency Induced Polarization Instrument measures subsurface electrical properties for groundwater detection, mineral exploration, and engineering geology investigations. The WDJD-3A system features CMOS large-scale integrated circuitry delivering ±6V voltage measurements with ±5‰ accuracy when Vp exceeds 10mV. Input impedance reaches 50 megaohms or higher, minimizing signal distortion during resistivity profiling. The unit measures multiple parameters including primary voltage (VP), induced polarization (IP), self-potential (SP), apparent resistivity (RO), polarizability (M), and time constant (TH) through a single survey pass.
Transmitting capability reaches 4500W maximum power with ±900V voltage and ±5A current output. Pulse width adjusts from 1 to 60 seconds with 1:1 duty ratio for controlled subsurface current injection. The system suppresses 50Hz industrial interference by 80dB or greater, maintaining measurement integrity near power transmission lines. Eight D-size batteries power the 7-kilogram unit measuring 310mm x 210mm x 210mm, operating from -10°C to +50°C in 95% relative humidity. Data protection circuits preserve measurements during power interruptions. Earth resistance checking verifies electrode contact quality before survey initiation.
Hydrogeological surveys employ the Dual Frequency Induced Polarization Instrument to map aquifer boundaries and determine groundwater quality through chargeability measurements. Mining exploration teams detect sulfide ore bodies and disseminated mineral deposits based on induced polarization anomalies. Railway engineering projects evaluate foundation stability by identifying weak zones and cavities beneath proposed track alignments. Dam construction surveys assess bedrock integrity, locating fracture systems that threaten water retention.
Tactical Supply Pakistan provides geophysical survey equipment for subsurface investigation and resource exploration projects. The company offers field training on electrode array configurations and data interpretation techniques for resistivity surveys.
How does induced polarization measurement distinguish metallic minerals from non-conductive geological features?
Metallic sulfides and graphite exhibit chargeability when current ceases, releasing stored electrical energy gradually versus instantaneous voltage decay in non-polarizable formations, creating distinctive IP anomalies that identify conductive ore zones.
