GeoSIG has a broad expertise on digitizers and recorders. Below are the mainstream product line for their most popular instruments for digitizing and storing data.
IA-1 Internet Accelerograph
The Internet Accelerograph opens a new era in the urban seismic research and engineering, which requires a high spatial density of seismic instruments. An instrument offered to the market in close co-operation with Pacific GeoScience Centre of the Geological Survey of Canada, the state of the art, all- in-one Internet Accelerograph. Encompassing a three component acceleration sensor, it is self-contained and equipped with an uninterruptable power-supply, which provides for more than six hours emergency operation without external power. The instrument and communication design takes advantage of the existing Internet infrastructure for timing, station management, data retrieval and event-reporting. Operating costs become significantly lower than conventional strong-motion seismograph networks.
GSR-12PC / GSR 16PC Recoders
The GSR-12PC/GSR-16PC Seismic Recorder is a high performance PC based Data Acquisition System for a wide application field using the GeoDAS data acquisition and data analysis software. GeoDAS offers data acquisition facilities as well as comprehensive data analysis tools. It provides a complete solution to researchers for seismic profiling, after shock studies, noise measurements, vibration measurements and structural monitoring. The GSR-12PC/GSR-16PC in combination with GeoDAS is the ideal, compact and extremely cost effective PC-based recording approach.
GSR-24 Seismic Recorder / GSD-24 Seismic Digitizer
The new state of the art GSR-24 Seismic Recorder has a three component 24 Bit high resolution digitizer capable of recording velocity and acceleration signals over 133 dB dynamic range. This high performance allows the acquisition of micro seismic, broad band and strong motion signals in a single field unit. Combined with the Radio Telemetry Interface and the acquisition facilities a complete cost effective solution for seismic profiling, after shock studies, noise measurements and single station micro seismic networks is offered. Digitized data stream output may be connected to a radio transmitter enabling continuous data transmission back to base and triggered recording into a up to 64 Mb ATA PC compatible flash memory.
GeoSIG GSR-18 Strong Motion Recorder /
GSD-18 Digitiser
The GSR-18 Strong Motion Recorder has a dynamic range of 111 dB @ 100 SPS and 108 dB @ 200 SPS. The standard 3 channel system has selectable sampling rates from 100 to 250 SPS. A variety of sensors can be connected to the GSR-18 offering solutions for applications in miscellaneous fields. The 18 Bit technology brings an additional dynamic range improvement in combination with the AC series of force balance sensors.
