Geophysical Electrical Prospecting Instrument for High Power IP Survey System

                                                 Geophysical Electrical Prospecting Instrument for  High Power IP Survey System

Main configuration:

A-DJF5-2 high power IP survey system is mainly consisted with generator, rectifying voltage boosting source, 1 set transmitter, 1~7 sets receivers, simulator, dummy load, cable, electrodes, software and so on.

1. Main application:

 high power IP survey system rectifies 220V/AC power to produce voltage supply that can reaches 1000V/DC. It supplies power to earth; the relative parameters with apparent resistivity and polarizability will display through receiver’s receipt and processing. Then we can make judgment according to basic theory of resistivity method and IP method and anomalous change of different geological bodies. It is mainly used in detailed or general survey of metal ores and non-metal ores.

2. Main features:

1. The transmitter, rectifier and receiver are split. One transmitter can configure 7 receivers maximum for simultaneous usage to improve efficiency and flexibility of electrode arrays.
2. Transmitter and receiver is time zone simultaneously controlled, and they store data separately for data processing and analysis.
3.  Micro-PC control, large LCD display. Receiver can store current supply timely touch, with RS-232 serial interface; it can connect with computer for data transmission and calculate apparent resistivity by software.
4.  High voltage and heavy currency supply system can meet demand in different prospecting depth. It also has over-voltage and over-current protection function.

5.  The system is new advanced product, which is integrated with geophysics, electronics, computer technology and information processing technique, and mainly faces to the application field of hydrology, mineral geology, engineering geology, energy geology and environmental geology etc.

4. Function and features of micro-power inspection transmitter (simulator):

As the signal receiving source, it can check whether the receiver is working normally or not.

Can be the micro-power transmitter to prospect rock sample or field ore outcropping (matching receiver).

Can be used for receiver adjustment.

5. Dummy load application:

The high power rectifier of the device’s transmitter as square wave signal with ratio 1:1 can supply power to the earth through rectifying the 220V AC power produced by the generator to HV DC power. During stopping power supply, the generator is in a status of no-load, which may cause runaway, so the generator should supply power to dummy load to keep the balance at that period.

It has 10 classifications: 24Ω,48Ω,72Ω,96Ω,120Ω,144Ω,168Ω,192Ω,216Ω,240Ω etc, the maximum bearing current (I)=6A.
