LOW FREQUENCY STAND FOR CALIBRATION AND TESTING OF ACCELEROMETERS AND SEISMIC RECEIVERS Russian patent published in 2021 - IPC G01P21/00 

FIELD: calibration and testing equipment.

SUBSTANCE: low frequency stand for calibration and testing of accelerometers and seismic receivers additionally contains a contactless electric drive that drives a movable rotating platform, balancing weights mounted on a movable rotating platform, and an electronics unit consisting of an internal power source, a lowering converter, a microcontroller, a humidity and temperature sensor, an information display and a digital input for connecting to a computer. A block of micromechanical sensors is installed on the movable platform to control its angular position and control the angular position of two semi-axes on which the movable platform is fixed, relatively to the horizon plane.

EFFECT: technical result is a simplification of the calibration process, a reduction in time of calibration by the operator, and an increase in the information content of the stand.
