Hydrophone

Ultra-compact receive-only transducer

Needle hydrophones

Large-diameter hydrophones

Features

A hydrophone is a transducer, which is specially designed for receiving ultrasound. It can receive ultrasound of wide frequency range at high resolution in water in order to measure the acoustic field.
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.

  • Needle hydrophone model: HY05N
    When spatial resolution is required
  • Large-diameter hydrophone model H9C
    When high sensitivity is required
