DEVELOPMENT OF A HIGH-SPEED MULTICHANNEL IMPEDANCE MEASURING SYSTEM

Tiago Piovesan Vendruscolo, Marco Jose da Silva

Abstract

Impedance sensors are found in many industrial applications. Multipoint and fast impedance measurement is required for some applications, for instance in the investigation of multiphase flows or the measurement of distributed sensors. In this paper, we describe a new highspeed multichannel impedance measuring system, which may be used for the evaluation of capacitance and resistive loss of multiple sensors. System is based on measurement at two selectable single frequencies. The system was evaluated against reference measurement showing good agreement.
