Product Description

Factory Price Geophone Seismic Sensor Seismograph Geophone Velocity Seismic Sensor Seismic Survey Geophone Horizontal Geophone Vertical Geophone

The geophone, also known as the seismic sensor or seismograph, has a wide range of applications, including but not limited to:

1. Seismic Surveys: Essential for both active (controlled seismic sources) and passive (ambient noise) surveys to map subsurface structures.
2. Vibration Assessment: Measures Peak Particle Velocity (PPV) to evaluate ground motion effects on infrastructure.
3. Surface-Waves Analysis: Employed methods like Multi-Channel Analysis of Surface Waves (MASW) and VS30 assessments for soil characterization.
4. Seismic Exploration: Used extensively in oil and gas exploration to detect subsurface structures and potential hydrocarbon reserves.
5. Earthquake Monitoring: Deployed in seismic networks to monitor and study earthquake activity for hazard assessment and research.
6. Civil Engineering: Employed for assessing ground stability and dynamic properties of soil for construction projects.
7. Vibration Analysis: Measures ground vibrations caused by human activities (e.g., construction, traffic) to evaluate their impact on nearby structures.

2.0 Hz three-component geophone is an electromechanical changeover device (sensor). Three 2.0 Hz geophones are orthogonally arranged (a vertical and two horizontal geophones) inside a sealed case, which indicate vertically for the Z-axis, east for the X-axis and north for Y-axis respectively. It is designed to receive seismic signals simultaneously from three dimensions and convert them into electrical pulses. It has such good characters as high sensitivity, high accuracy, perfect damp factor,good consistency, solid structure, good seal and water-proof capability. There is a leveling bubble on the cover and a direction indication on the seismometer. It can be used with a deep seismograph to detect seismic activity in applications such as earthquake prediction, structural analysis, etc.
