Micro-Seismicity Monitoring Instrumentation SRi32L Compact Sensor/Digitizer/Recorder Unit
Portable Seismic Stations
Overview
GEObit provides compact solutions for quick-deploy seismic stations based on the GEOThree digitizer/recorder and C100 sensor. The GEOThree recorder has three input channels and integrated sensor electronics. The digitizer is based on a powerful, wide dynamic range 32-bit delta-sigma analog-to-digital converter, with very low noise characteristics and excellent power supply rejection. The sampling rate can be set to 50, 100, 200, 250, 500, and 1000 samples per second. The sensor response is 10sec – 98Hz. The data are stored in a removable microSD card. Ultra-low power consumption allows over one month of operation when powered by an ordinary 12V/65Ah lead-acid battery.
The LCD displays the State-of-Health, time, date, and other information about the instrument’s operation. The digitizer is intended for installation in harsh environments. The instrument supports an embedded SEEDlink server for real-time data telemetry.
+ Applications
- Aftershock studies
- Local and regional seismicity monitoring
- Seismic Tomography
- Reservoir monitoring
- Induced seismicity monitoring
- Geothermal monitoring
- Structural monitoring (Dams, Bridges, Ancient Castles)
Here we present the instrumentation used in several passive tomography projects as well as several micro-seismicity and induced seismicity projects, and explain why we propose using this kind of equipment.
