1. A system for determining coil eccentricity of one or more seismic sensor configured or designed for use in seismic signal detection, comprising:
- at least one seismic sensor, comprising;
a housing;
at least one magnet for creating a magnetic field mounted within the housing;
a moving coil mounted within the housing;
at least one spring assembly connected to the housing and the moving coil for supporting the moving coil for transduction within the magnetic field;
a digital signal processor in communication with the seismic sensor;
a set of instructions executable by the processor that, when executed;
applies to the moving coil of the at least one seismic sensor a direct electrical current such that the moving coil is dislocated from a neutral position relative to the magnetic field in the seismic sensor;
monitors a predetermined indicator relative to the dislocation of the coil from the neutral position; and
determines eccentricity of the coil (δ
) relative to the center of the magnetic filed using the predetermined indicator.

Abstract
Methods and systems for determining coil eccentricity of seismic sensors configured or designed for use in seismic signal detection. A direct electrical current is applied to a moving coil of a seismic sensor such that the moving coil is dislocated from a neutral position relative to the magnetic field in the seismic sensor. A predetermined indicator is measured and eccentricity of the coil (δ) relative to the center of the magnetic filed is determined using the predetermined indicator.
