Abstract: The piezoelectric crystal sensors used the characteristic that the oscillation frequency of the piezoelectric crystal is highly sensitive to the load and properties on crystal surface, such as density, viscosity, conductivity and dielectric constant to carry out materials micro-quality test. Introduction was made to the principle of the piezoelectric crystal sensors. This paper designed the hardware composition, data processing and analysis software of the detection system and analyzed the system’s application actuality, looking forward to the development trend of the detection system.
        Key words: piezoelectric crystal sensor; micro-quality; detection system
