SEISMOMETER Russian patent published in 2013 - IPC G01V1/16 

FIELD: physics.

SUBSTANCE: disclosed is seismometer, having a base, two elastic members, a support arm, two magnetic systems, a multi-section coil lying between magnetic conductors and pole terminals of the magnetic systems, a sinusoidal generator and an amplifier. The seismometer also has a capacitive sensor with exciting electrodes, a first output electrode and a second output electrode, two magnetically soft rods and two dielectric spacers. The design of the disclosed device is supplemented by a transformer.

EFFECT: high signal-to-noise ratio at the output of the seismometer and, consequently, high accuracy of measuring seismic forces.
