Abstract
A 5 MHz AT-cut quartz-crystal resonator has been totally immersed in distilled water at different temperatures between 5 and 95°C. The oscillation has been characterized by an impedance analyzer around the fundamental frequency. The complex impedance has been found to increase with rising water temperature. An equivalent circuit including inductance, resistance and capacitance has been designed to simulate the experimental data within an error of 3.5%. The simulated parameters (resistance, capacitance, inductance, etc.) have been related to the physical properties of water by comparison with literature data. This fundamental approach results in the realization of a simple and cheap monitor for practical use in continuously detecting the general pollution of waste water in terms of the impedance modulus and resonance frequency of the immersed quartz resonator.
