Connectable to SCADA systems


of ZET 048-E seismic stations

ZET 048-E Seismic station is designed for measuring and recording the signals from seismic receivers.

The recording systems can be used offline or within the automated systems for conducting seismic and seismological research, onshore and offshore works, at sea bottom and on ice, using the methods of refraction and reflection waves and deep-water seismic sounding against the man-made and natural sources, using the seismology and the earthquake converted-wave method, as well as during geotechnical surveys.

The digitized signals are processed using the fully functional software ZETLAB SEISMO.

Application scope

of ZET 048-E seismic stations


of ZET 048-E seismic stations

Seismic digital seismic logger

ZET 048-E Seismic station is a 24-bit digital conversion module that ensures high quality and reliability of seismic signal conversion.

Digital conversion on each channel is performed by an independent analog-to-digital conversion chip.

Practical application

of ZET 048-E seismic stations

ZET 048-E Seismic station together with an analog field streamer can be used for seismic surveys.

The seismic event recording can be triggered by an impact hammer: mechanical oscillations are excited by impact hammer, geophones convert mechanical oscillations into an electrical signal and transfer it via the streamer line to the seismic station, which records and processes the signal.
