Accurate, low-noise processing of the sensor signals that are emitted is essential to obtain measurement results that can be utilized. Kistler offers an attractive portfolio of solutions for signal processing and subsequent data digitization. Piezoelectric sensors (PE sensors) with a charge output operate reliably with charge amplifiers. On the other hand, piezoelectric sensors with integrated electronics (IEPE sensors) are supplied by Piezotron® couplers which decouple and amplify the signal.
