PVDF-ST-1-P型水听器适用于作100kHz～1MHz频段内的标准水听器,其平均灵敏度为-204dB,频响起伏±1.5dB。它还成功地用于检测速度为50m/s的冲急水流的空化噪声频谱。本文论述了这种仪器的结构设计、性能和应用范围。
PVDF-ST-1-P hydrophone for the standard hydrophone 100kHz ~ 1MHz band, the average sensitivity of -204dB, frequency fluctuations ± 1.5dB. It has also been successfully used to detect the cavitation noise spectrum of rush currents of 50 m / s. This article discusses the structural design, performance and application of this instrument.
