Measurement Time Optimization of Impedance Spectroscopy Techniques Applied to a Vibrating Wire Viscosity Sensor

José Santos, Fernando M. Janeiro, Pedro M. Ramos

Abstract

This paper describes the optimization of the measurement time of the impedance frequency response of a vibrating wire sensor for viscosity estimation. The optimization deals with the assessment of the estimated viscosity as a function of the number of measured impedance frequency points as well as the selection of those frequencies. This speed optimization is important to ensure that the viscosity measurements are influenced as little as possible by external environmental parameters such as temperature and pressure.
