8-CHANNEL RECEIVER IMVP FOR INDUCED POLARIZATION METHOD

New product

Multi-channel electrical exploration receiver IMVP is designed for carrying out works by the induced polarization (VP) method in the frequency and/or time domain.

More details

More info

Multi-channel electrical exploration receiver IMVP is designed for carrying out works by the induced polarization (VP) method in the frequency and/or time domain. It may also be used when carrying out works with the of the constant current (resistances), frequency sounding (ChZ) method, and a differentially normalized method of electrical exploration (DNME).

 

Features

The reciever simultaneously records a signal with 8 MN receiver circuits, where the M electrode for one receiver circuit may serve as N electrode of the next one

All wires may be united in one 8-channel bunch or two bunches, 4 channel in each

The receiver always operates jointly with a PC (notebook computer): the PC is used to control the receiver and record the signal

Communication with the PC is performed via the USB interface

 

Advantages

IMVP provides for increasing labor productivity, reducing work costs and increasing the information content of the induced polarization method

This is state-of the-art, portable, free-running, multi-channel and high-precision equipment

The increase of the method information content is achieved due to response registration both in the frequency domain (INFAZ-VP method) in a wide frequency range and in the time domain.

High precision of registration (the receiver is equipped with 24-bit  ADC in each channel) and long-time continuous recording with a rather narrow sampling increment (2500 Hz) make it possible to use different algorithms for studying the time-and-frequency characteristics of the induced polarization process

The time-and-frequency relations of the induced polarization provide for distinguishing between different types of rocks and ofe minerals.
