Title:Improving the Precision of a Compact Subsampling Impedance Analyzer for Resonating SensorsAuthor(s):Alexander Niedermayer, Thomas Voglhuber-Brunnmaier, Erwin Reichel, Bernhard JakobyAbstract: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.Booktitle:Proceedings of the Eurosensors XXIII conferencePage Reference:4 page(s)Publishing:5/2009
