DEVICE FOR MEASURING INFRASOUND VIBRATIONS OF THE MEDIUM Russian patent published in 2022 - IPC G01V1/16 G01H11/06 G01P15/125 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology, in particular to the field of measurement of infrasound vibrations of a gaseous or liquid medium. A device for measuring infrasound vibrations of the medium is claimed, containing a housing, capacitive sensors for the movement of a sensitive element associated with the nearby environment and the environment inside the housing, an electronics unit including the first amplifier and demodulator connected to a generator connected to capacitive sensors, as well as a second amplifier and filter. Additionally, the device contains a tubular cylinder inside the housing, a longitudinal partition, the first and second bases, the first and second disc throttles, two support rings, a thread, a tension sleeve, a bracket, an adjustment screw, a lock nut, two dust filters, two covers, a magnetoelectric converter and a pre-amplifier. The tubular cylinder is made of heat-insulating material, the sensing element is made of magnetic material, and the capacitive sensors are made of non-magnetic material.

EFFECT: increase in the accuracy of measurement of infrasound vibrations of the medium.
