Hydrophone

Ultra-compact receive-only transducer

A hydrophone is an ultra-compact, receive-only transducer that is specially designed for measuring underwater ultrasound acoustic fields. It has a high resolution and is capable of measuring a wide range of frequencies.It uses Toray’s unique P (VDF-TrFE) polymer piezoelectric material.
The acoustic impedance is close to that of water, so there is minimal difference in sensitivity between resonant and non-resonant frequencies. It has a large resonance peak, accurately reproducing incident waves over a wide range.
It has a wide incidence angle tolerance, making it easy to adjust the hydrophone’s angle.
It is made with polymer material with a high electromechanical coupling factor and upper usage temperature limit, and is highly resistant to temperature changes, offering a stable, high level of performance.
