WHAT A GEOPHONE DOESA geophone converts seismic energy inputs (or vibrations) into electrical voltage which can be accurately measured. When vibration of any sort moves the case, the coil remains stationary due to its inertia. This movement of the case in relation to the stationary coil generates an electrical voltage proportional to the velocity of the coil with respect to the case. The instrument itself is based on a magnetic coil suspended by springs within a steel case. Measuring variations in the electrical current provides the data to determine the amount or intensity of the vibration. OFS geophones are uniquely designed with a rotating coil, reducing harmonic distortion and greatly extending the working life of the product. Often competitor products employ ‘pigtail' springs to connect the suspended coil to the external connections. However, this design is highly susceptible to multi component vibration damage. No power source is necessary and amplification of the signal is not required.
