A 821

  • Charge Preamplifier

  • A 821 is a charge preamplifier. Its function is to convert the high‑impedance charge signal generated by charge‑type piezoelectric sensors into a low‑impedance voltage signal, enabling such sensors to be used with IEPE power supplies.

    A 821 can be applied to various charge‑type piezoelectric sensors, including charge‑type piezoelectric accelerometers, force sensors, and pressure sensors, giving it a wide range of applications.
