ELECTRO PROSPECTING HIGH FREQUENCY STATION «VEGA»

The Electro prospecting high-frequency system Vega is a resistivity instrument which provides high quality data on the electrical properties of soil, using traditional resistivity measurements, but without the possibility of grounding.

The Electro prospecting high-frequency system Vega is a resistivity instrument which provides high quality data on the electrical properties of soil, using traditional resistivity measurements, but without the possibility of grounding.

Features:

Wireless data exchange between the transmitter, the receiver and the control unit;

Mobility and easy usage;

Continuous gathering of information on geologic cross-section;

High quality performance without the possibility of grounding;

Compact and robust design for tough field conditions;

One year warranty;

After-sales service;

Online consultation.

Application:

Examining near-surface geologic cross-section;

Detecting defects inside a building's structure;

Measuring pile length;

Microzonation survey;

Monitoring of buildings which are prone to vibration (hydro power-plant, oil production plant, etc).

 

CONFIGURATIONS:

Vega consists of a transmitter, a receiver, a control unit and a 2.5 meter antenna. The transmitter is connected to the receiver via a cable.

The transmitter and the receiver(s) are located at the surface in a line. The control unit receives data from the transmitter via a wireless modem. The operator can see the results of the transmitter and the receiver(s) and calculate the resistivity in real time. All data is instantly recorded to an internal Flash card. The collected data is processed using our custom designed software.
