ULTRASOUND ECHO-PULSE DEPTH METER Russian patent published in 1997 - IPC

Abstract RU 2082161 C1

FIELD: non- destructive flaw-detection. SUBSTANCE: device has probing pulse generator 1, which output is connected to emitter 2 and input of synchronization pulse oscillator 3, which output is connected to synchronization input of time-to-code converter 4. In addition device has receiving detector 5 which is connected to input of amplifier 6 which output is connected to input of time-to-code converter 4, which output is connected to first input of digital comparator 7 and input of memory register 8, which output is connected to second input of digital comparator 7, which output is connected to writing permission input of memory register 8. Output of memory register 8 is connected to input of digital indicator 9. EFFECT: increased precision. 1 dwg
