Abstract
Effect of heating times on piezoelectric sensing of engine oil has been investigated with different heating times (0, 15, 30, 45 and 60) min. Sensing signals (piezoelectric) characterized and achieved by using transducer which transmits a mechanical waves towards the glucose solution cell, and then the receptor received the attenuated signals. The range of operating frequencies was (950 kHz - 50MHz), the results of measurement which included recording the resonance frequencies (in the first order) for all prepared samples. The results showed that the resonance frequency shifted to the higher values (from 12MHz to 26MHz) for heating times (from 0 to 60 min) of engine oil.
