FIELD: measurement technology. SUBSTANCE: device has series-connected vibration transducer 1, amplifier 2, unit 3 for processing vibroacoustic signals and recording device 4. Unit 3 in turn has analogue-to-digital converter 5 connected to the output of amplifier 2, digital-to-analog converter 6 connected to recording unit 4, series connected two-input adder 7, digital multiplier 8 and controllable delay line 9 the output of which is connected to the first input of adder 7 the second input of which is connected to the output of analogue-to-digital converter 5. The output of digital multiplier 8 is connected to the input of digital-to-analogue converter 6 and control input of delay line 9 through series-connected digital frequency multiplier 10 and pulse shaper 11 is connected to cycle phase sensor 12. EFFECT: enhanced reliability. 1 dwg
