Oscillation Conditions for An Electrode-separated Piezoelectric Sensor in Electrolyte Solution

摘要

Based on the needs of the oscillation equation and frequency stability, three oscillation conditions are proposed and have been experimentally verified for an electrode-separated piezoelectric sensor (ESPS ) in electrolyte solutions. The present paper covers the dependence of the minimum cell constant needed for the ESPS on solution conductivity. The oscillation conditions of the classical liquid piezoelectric sensor are discussed. The "cease-to-oscillate" frequencies of the ESPS were measured.
