Seismic Sensor Working
Principle
Seismic sensors work by
utilizing mass-spring systems and transduction mechanisms to convert ground vibrations into electrical signals. These signals are then processed and analyzed to extract valuable information about
seismic events and the subsurface properties.
●Mass-Spring
System: Seismic sensors typically consist of a mass-spring system. This system comprises a heavy mass (the seismic mass) attached to a spring or set of springs. The mass is designed to be
sensitive to even the smallest ground vibrations.
●Inertial Motion: When
seismic waves propagate through the Earth, they cause the ground to move back and forth or up and down. This motion is transferred to the seismic mass of the sensor.
●Relative Motion: The
mass-spring system within the sensor is engineered to resist motion. As the ground moves, the inertia of the seismic mass resists this motion, causing relative displacement between the mass and
the sensor's frame.
●Transduction
Mechanism: To convert the relative motion into an electrical signal, seismic sensors employ various transduction mechanisms. One common method is the use of electromagnetic induction. This
involves a coil of wire attached to the seismic mass and positioned within a magnetic field. As the mass moves relative to the coil, it induces an electrical current in the wire.
●Electrical Signal
Generation: The induced electrical current is proportional to the displacement or velocity of the seismic mass. This electrical signal represents the ground vibrations and is then amplified,
digitized, and recorded for further analysis.
●Signal Analysis: The
recorded electrical signals from multiple seismic sensors are processed and analyzed to determine the characteristics of the seismic waves. This analysis includes studying the amplitude,
frequency, and arrival time of the waves, providing valuable insights into the properties of the subsurface, such as the location and magnitude of seismic events or the structure of geological
formations.
