SEISMOGRAPH CALIBRATION METHOD Russian patent published in 2017 - IPC G01V13/00 G01V1/16 G01N29/30 

FIELD: measuring equipment.

SUBSTANCE: method of calibrating seismographs is proposed, according to which the plates of the electrostrictive material are placed between the pedestal and the seismograph, while a sealed tank is mounted on the pedestal, at the bottom of which the plates of the electrostrictive material are placed, on which the sealed container is mounted. The seismograph is mounted at the bottom of the sealed container, and the volume formed by the tank and the sealed container is filled with liquid.

EFFECT: simplifying the seismograph calibration procedure, improving the accuracy of the seismograph calibration.
