TWO-COMPONENT VIBRATION-FREQUENCY ACCELERATION CONVERTER Russian patent published in 2025 - IPC G01P15/97 

FIELD: measuring equipment.

SUBSTANCE: two-component vibration-frequency acceleration transducer comprises an elastic element equipped with an additional inertial mass, which is connected to a support base through elastic suspensions, wherein the resonator is connected on the other side with an additional inertial mass, in addition, the converter is equipped with a second elastic element, a second system for exciting and recording oscillations and a second background voltage compensation system, each second component is identical to the first one, wherein the second elastic element and the second vibration excitation and recording system are located on the opposite side of the base, so that during acceleration along the sensitivity axis of the transducer, the resonator of the elastic element is compressed under the action of a force from the side of the inertial mass, and the resonator of the second elastic element is stretched under the action of force from the side of the inertial mass.

EFFECT: high accuracy of converting acceleration with simultaneous increase in resistance to change in ambient temperature.
