Zibo Yuhai Electronic Ceramic Co., Ltd.
We manufacture an extensive selection of piezoelectric elements from our specially formulated, highest purity lead zirconate / lead titanate ceramics. Use an soft (sensor) ceramic -PZT-5 or PZT-5H - for low-power resonance or non-resonance devices, when high coupling and/or high charge sensitivity are important. Choose an hard (high power) ceramic - PZT-4 series, or PZT-8 - when high power characteristics are required.
PZT-5 seires (PZT-51, PLiS-51, PSnN-5) is an excellent piezoelectric material for flow or level sensors, such as ultrasonic or Doppler flow meters, gas flow sensors, and ultrasonic level sensors, for ultrasonic NDT / NDE applications, or for accurate inspections of automotive, structural, or aerospace products (construction materials, structural welds, transmission lines, steel storage tanks). They are also ideal for high performance transducers for medical imaging applications. A high dielectric constant, high coupling, high charge sensitivity, high density with a fine grain structure, a high Curie point, and a clean, noise-free frequency response are characteristic of PZT-5 seires.
PZT-52, 53 and PZT-5H is well suited to applications similar to those in which APC 850 is used, when high permitivity and high piezoelectric charge coefficients are required.
PZT-4 series materials are widely used for generating ultrasonic or high-voltage energy in ultrasonic power, sonar market, etc. Important characteristics of PZT-4 include a high piezoelectric charge constant (d33) relative to reference values for this formulation, greater power output per volume of material, a high mechanical quality factor that reduces mechanical loss and allows a lower operating temperature, and a low dissipation factor that ensures cooler, more economical operation.
High dielectric stability and low mechanical loss under demanding conditions make PZT -8 an excellent choice when the highest electrical drive is required.
