Abstract

In recent years, compact and precise impedance measurement electronics have proved to be reasonable alternatives for dedicated measurement tasks like impedance measurement of resonant sensors. In this contribution, the design of a compact subsampling impedance analyzer is discussed. Furthermore the target application, a quartz crystal resonator (QCR) viscosity sensor for conductive liquids, as intended for the monitoring of a zeolite synthesis process aboard the International Space Station (ISS), is presented. In particular, accuracy aspects of the involved signal processing stage are examined.
