Basic Info

    Model No.: OD27.94*ID8.5*200KHz BaTiO3

Product Description

Piezoelectric ceramic ring

Lead free Piezo Ceramic Ring

Yuhai company developped Piezo material BaTiO3. Its high stiffness and low dissipation factor under high electric field make it special for sonar etc. .

Barium titanate lead-free piezoelectric ceramics are important piezo materials for the development of modern science and technology, which was widely used in the manufacture of ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic transformers, ceramic frequency discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, ignition and detonation devices, and piezoelectric gyroscope etc.

Application: military, ocean, fishery, scientific research, mine detection, daily life and other fields.

Application: Ultrasonic Transducer (fishfinder)

Piezoelectric ceramic Material: BaTiO3 (lead free)
