ULTRASONIC PHASE TRANSDUCER OF ANGULAR TURNOVER Russian patent published in 2018 - IPC G01B17/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring technology and can be used to measure the parameters of vibrations, angular speeds of rotation of shafts in various branches of engineering. Ultrasonic phase transducer of the shaft rotation angle contains a series-connected master oscillator, power amplifier, radiating transducer, object under study, receiving transducer, matching amplifier, the outputs of the master oscillator and the matching amplifier through the meander drivers are connected to the first multiplier, and its output is connected to the first input of the second multiplier, the second input of which is connected to the output of the clock generator, and the output through the information processing unit is connected to a digital-to-analog converter, to the third input of the second multiplier unit, the output of the receiving converter is connected through a series-connected spectrum analyzer and a square wave generator.

EFFECT: technical result, achieved in the implementation of the claimed device is to expand the functionality by measuring the unbalance of rigid rotors with a complex configuration of increasing the accuracy of measuring the angles of rotation of the shaft.
