Multi-electrode geoelectrical solution SibeR is meant to combine the functions of transmitter, multi-channel receiver and switch in single protective housing. The device is designed for electrical resistivity tomography (ERT) and vertical electrical sounding (VES) via resistivity method and IP or for electrical logging. Our company manufactures reinforced sealed cable systems for electrical surveys with any electrode spacing that is perfectly compatible with SibeR.
SibeR has the following features that improve data quality and performance:Three versions of SibeR vary not only in the number of switched electrodes (from 32 to 64), but also in the output power of transmitters: 120 or 220 W. SibeR 64K15 has also the capability to connect an external 1000 W transmitter.
The instrument can be controlled by PC or tablet via Wi-Fi connection or Ethernet. The Xeris measurement control software is designed for Windows (7.0 and higher), Linux and Android (5.0 and higher) devices. In addition to measurement triggering and control functions, the program allows data filtering and storage of user-created measurement protocols, including a combination of several arrays - Schlumberger, dipole-dipole, three-electrode (forward and reverse), two-electrode and others. Voltage, pulse duration, number of accumulations and other settings can be varied during measurements. It is also possible to specify the exact coordinates of remote electrodes, which are to be considered at subsequent data processing stage.
When processing IP data, it is possible to extract from the recorded signal any time intervals at multiples of 20 ms.
In order to spread the profile there is a mode of expanding it with an overlap of neighboring layouts by a quarter.
Output data formats are compatible with popular postprocessing programs: e.x. ZondRes2D or ZondRes3D.
