Digital Seismic Seismograph with 4.5Hz geophone (EPS)
Seismic equipment is used to study the earth's subsurface by
generating and recording signals that travel through the earth.
These signals can be used to create images and maps of the
underground rocks and formations, and to identify potential sites
for drilling or mining.
1. Geophone: A digital seismograph requires at least one
seismometer geophone to measure ground vibrations. The sensor
should be stable, sensitive, rugged, and have a low noise level.
2. A/D Converter: A digital seismograph must have an analog to
digital (A/D) converter to convert the analog output from the
sensor into a digital signal.
3. GPS Receiver: A GPS receiver is needed to provide precise timing
and location of seismic events.
4. Data Storage: A digital seismograph requires a data storage
system capable of storing large amounts of data. This may include
internal or external memory, hard disks, solid-state drives, or
other storage devices.
5. Software: Seismograph software is critical for analyzing and
interpreting the seismic data. The software should be
user-friendly, allow data management, and offer advanced analysis
and display tools.
6. Connectivity: The seismograph should have connectivity options,
such as USB, Ethernet, or Wi-Fi, for data transfer and remote
operation.
7. Robustness: The seismograph should be durable and able to
withstand harsh environmental conditions, as it may be deployed in
remote and challenging locations.
8. Calibration: A digital seismograph must be periodically
calibrated to ensure accurate measurements.
