Zusammenfassung: | The high-precision hygroscope is composed of crystal, electrode plate on crystal, leading line, chemical film plated with special technology and external circuit. The crystal after turned on resonates with external circuit because of its converse piezoelectric effect to generate a fixed frequency. The properties of chemical film change when ambient humidity varies, making resonant frequency change. Measurement of the frequency can obtain corresponding humidity value. |
