Yet another precision impedance analyzer (YAPIA)—Readout electronics for resonating sensors

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, a novel design of a compact impedance analyzer is discussed, and 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.
