DEVICE FOR MEASURING INFRASONIC OSCILLATIONS OF THE MEDIUM Russian patent published in 2022 - IPC G01H11/00 G01H11/06 

FIELD: infrasonic oscillations measuring.

SUBSTANCE: invention relates to the field of measuring infrasonic oscillations of a gaseous or liquid medium. The device for measuring infrasonic oscillations of the medium contains a housing, capacitive sensors for moving a sensitive element connected to the environment and the medium inside the housing, an electronics unit that includes a first amplifier, a demodulator, a generator, capacitive sensors, a second amplifier and a first filter. The housing inside contains a tubular cylinder, a longitudinal baffle, the first and second bases, the first and second disk chokes, two support rings, a thread, a tension sleeve, a bracket, an adjusting screw, a lock nut, two dust filters, two covers, a magnetoelectric converter, a preamplifier, the first and a second temperature sensors and two gaskets. The electronics unit includes a third amplifier, a fourth amplifier, a first subtractor, a second filter, and a second subtractor.

EFFECT: increased accuracy of measurement of infrasonic oscillations of the medium.
