Digtal and Light Weight Seismograph
Application
It is more widely used in research areas such as intensive
earthquake networks and natural seismic observations, reservoir
induced earthquake monitoring, mining earthquake monitoring and oil
and gas exploration, and other broadband zone earthquake
observations and underground formation. Wait for scientific
investigations
Features
1. Integrates a variety of functions such as integrated broadband
seismic meters, collection, storage, data transmission, and
detection
2. Inside contains 32 -bit collectors, small broadband zone seismic
meters, data storage units, network communication, and GPS timing
units
3. The signal conversion of vertical, east -west, and north after
the coordinate is transformed.
4. The collector is used to collect the voltage signal of the
output of the sensor, including three high -resolution, large
dynamic range, and full balance differential channels of fast real
-time data flow output, and has high time and time -conservative
accuracy.
