OMEGA-48 is a multichannel resistivity system designed for vertical electrical sounding (VES) and induced polarization (IP) methods based on the electrical resistivity tomography (ERT) technology.
The OMEGA-48 resistivity system consists of
- multi-electrode 10-channel resistivity instrument which includes a transmitter, a receiver and a switching unit connected to current and measuring lines in a single heavy duty cable with a waterproof enclosure
- two sections of multi-core cable with 24 electrodes each
- industrial laptop
- software for system control, data acquisition, data processing and interpretation:
- field measuring protocol, SEQ files development
- measuring process, data collection and storage management
- field data visualization and editing
- automatic data 2D inversion
- visualization of inversion results
The resistivity instrument measures amplitude parameters of the output current of the transmitter, the electrical potential difference between measuring electrodes (apparent resistivity), time parameters of chargeability (apparent chargeability) determined on the voltage decay curve at measuring electrodes after the current is switched off.
