Abstract
PURPOSE: To increase the operating efficiency of a test tank by measuring plural wave transmitter/receiver sets for ultrasonic apparatus in one test tank, by controlling the wave transmission and wave reception timings.
CONSTITUTION: The measuring frequency signal from an oscillating circuit 4 is modulated 5 into a pulse waveform of tone burst, and is amplified 6 to be supplied into a wave transmitter/receiver 1 placed in a water tank 3. The sound wave generated in the wave transmitter/receiver 1 is received by a standard unit 2, of which output signal is amplified 6 and inputted into a pulse voltage measuring circuit 7 to be synchronously measured together with the input voltage of the transmitter/receiver 1, so that the sensitivity is calculated. Next, by changing the wave transmission direction of the wave transmitter/receiver 1, the sensitivity is measured, and the directivity is obtained. In this case, the sound pressure level is judged 10 according to the signal level from the wave receiver 11, and a trigger circuit 8 is controlled by the output of such judgement, so that the operation timing of the modulating circuit 5 and measuring circuit 7 may be controlled.
