 INTRUSION DETECTION- Security and surveillance systems employ
geophones to detect movement along borders, perimeters and in
buildings.
|
- MACHINERY ANALYSIS
- Geophones are mounted on strategic
locations to monitor machinery performance, wear and failure.
|
- MACHINERY BALANCING
- Geophones are used to analyze angular
motion and wobble in both fabrication and assembly of shafts, bearings and
flywheels.
|
- VIBRATION
MONITORING
- Measurement of vibration levels to
locate and position critical machinery and equipment in factories and offices.
Low-cost geophones are an ideal solution to this problem.
|
- STRUCTURAL EVALUATION
- Geophones detect seismic and
microseismic events to predict and analyze deformation of buildings, dams,
mines and bridges.
|
- MINING / ENVIRONMENTAL
- High resolution seismic surveying,
mining, and environmental.
