H9CN

Key device for sound field measurement

대구경 하이드로폰 H9CN

하이드로폰이란, 수중의 초음파의 음장을 측정하기 때문에 넓은 범위의 주파수의 초음파를 고분해능으로 측정할 수 있는 수신전용 초소형 트랜스튜서입니다. 대구경 하이드로폰은 고감도가 필요할때 적합합니다.

Features

• Element diameter : Φ 9.0 mm
• It is a polymer piezoelectric material that has been developed by TORAY uses the P(VDF-TrFE).
• Since the acoustic impedance is close to water, the sensitivity difference is small at the resonance frequency and the nonresonance frequency. The resonance peak is wide. Therefore, it reproduces a signal faithful to the incident wave over a wide range.
• Because the sound velocity difference at piezoelectric polymer film and water is small, easy to angular adjustment of the incidence acceptance angle is large hydrophone.
• In the polymer material, because the electro-mechanical coupling coefficient and use temperature upper limit is high material, and delivers a stable and high performance to the temperature change.
• Measurable frequency range is 0.5MHz ~ 10MHz.
