METHOD OF CALIBRATION OF THREE-COMPONENT INTERRUPTOR VIBRATORS Russian patent published in 2015 - IPC G01M7/06 

FIELD: instrumentation.

SUBSTANCE: invention relates to instrumentation and can be used for calibration of three-component interruptor vibrators. In compliance with claimed process, the reference interruptor vibrator and that to be gaged are subjected to preset unidirectional vibrational acceleration. Measured reactions to projections of vibrational accelerations of both interruptor vibrators are compared. Note here that said reference and verifiable interruptor vibrators are configured so that their like sensitivity axes are parallel. Vertical sensitivity axis of every interruptor vibrator is aligned with the plane extending through the vector of unidirectional vibrational acceleration acting on the interruptor vibrator and the bisector of angle between the interruptor vibrator horizontal sensitivity axes. Said axis is directed at preset acute angle to the vector of unidirectional vibrational acceleration acting on the interruptor vibrator and to the like sensitivity axes of verifiable and reference interruptor vibrator unidirectional accelerations. Said vectors are equal to their projections on the like sensitivity axes of verifiable and reference interruptor vibrators.

EFFECT: higher accuracy of calibration.
