DJF Series Underground Gold Detector High Power DC IP Measuring System

Main Applications and Features

1         High Power Direct Current IP Measuring System includes: receiver, time domain IP transmitter, rectification power, simulator and dummy load. The system is a high-tech product which integrated with geophysics, electronics, computer technology, information processing technology, aiming to hydro-geological, mineral geology, engineering geology, energy, geology, environmental geology applications.

2         For large areas of metal mining, non-metallic mineral resources, geological survey and detailed survey work, search for groundwater and other hydrological and engineering geological exploration.

3         The system transmitter has two synchronization mode (domestic initiation): delay synchronization after pulse and high-precision quartz clock synchronization, which allows high efficiency of field production, also convenient and flexible.

  DJS-8BHigh Power IP Receiver

1         Rapid and Accurate: By adopting pulse delay synchronization mode and high-precision quartz clock synchronization mode, more accurate power-off delay is enabled , precise polarization measurement is realized , thus overcome the enlarging problem of apparent polarization error caused by large judgement error in power-off time for similar instruments.

2         Automation: SCM (Single Chip Micyoco) automatically execute self-potential compensation, gain adjustment, filtering and signal enhancement.

3         Time Parameter Recording: DJS-8B has auto travel time function, with measuring time stored together with measured results to facilitate the calculation of apparent resistivity.

4         Extra-large Storage: 15,000 groups of measured values can be stored, no loss even in case of power failure

5         Strong Anti-interference Capability: Adopt signal enhancement technology to suppress the interference a, thus highlight the effective signals.

6         RS-232C serial port can work with microcomputer (PC) on-line.

7         Fault Diagnosis: Fault location and damaged device can be accurately identified.
