Piezoelectric Tube Acoustic Pickup OD23xID19x15mm

Basic Info

    Model No.: OD23 x ID19 x15mm PZT-52

Product Description

Piezoelectric ceramic tubes

Electrode direction: Radial direction



Applications: Underwater acoustic transducer hydrophone


Material: PZT-52 (High dielectric constant 2400 of PZT-5A)


PZT -52 is a modified soft PZT designed for relative high dielectric constant required hydrophone etc. receiver transducers


Soft PZT

High sensitivity or "soft" ceramics feature high sensitivity and permittivity, but under high drive conditions are susceptible to self heating beyond their operating temperature range . These materials are used in various pick-ups and sensors, low-power motor-type transducers, receivers, and low power generators.

PZT-5 series

The PZT -5 series materials are SOFT PZT , They range in Curie temperatures from 165°C to 350°C. All these materials have been optimised for charge constants or coupling coefficients for specific applications. PZT-5 series is often used as the receiver or generator element in hydrophones, accelerometers, and vibration sensors. PZT-5 Series is a lead zirconate titanate with a high sensitivity, permittivity, and time stability. PZT5H series is used in sensitive receivers and applications requiring fine movement control. It has been used in a wide range of applications from hydrophones to ink jet printers. PZT5H Series provides extremely high permittivity, coupling, and piezoelectric constant.
