Choosing an EPC Material

We manufacture an extensive selection of piezoelectric elements from our specially formulated, highest purity lead zirconate / lead titanate ceramics. Use an EPC soft (sensor) ceramic - APC 850, APC 855, or APC 856 - for low-power resonance or non-resonance devices, when high coupling and/or high charge sensitivity are important. Choose an EPC hard (high power) ceramic - APC 840, APC 841, or APC 880 - when high power characteristics are required.

APC 850 is an excellent 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). APC 850 also is 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 APC 850.

APC 855 and APC 856 are suited to applications similar to those in which APC 850 is used, when high permittivity and high piezoelectric charge coefficients are required. Although its properties are somewhat different from those of APC 850, APC 856 also is an excellent material for fluid flow sensors, level sensors, ultrasonic NDT / NDE applications, and medical imaging applications.

APC 840 and APC 841 materials are widely used for generating ultrasonic or high-voltage energy in ultrasonic cleaners, sonar devices, etc. Important characteristics of APC 841 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 APC 880 an excellent choice when the highest electrical drive is required.
