Establishment and Stability of the Platform for Detecting Oscillation Frequency of QCM

The stability of piezoelectric quartz crystal oscillator resonance frequency is to structures the prerequisite of measuring the platform of the crystal microbalance,the environment temperature is the main factor causing the frequency of the high steady quartz crystal oscillator of degree to drift about.Through theoretical analysis,technology structures the special vibration circuit to select the suitable chip for use,adopt difference frequently,caused by environment temperature of the platform and drifted about,thus improved the stability of the microbalance,has made the performance of the sensor obviously improved.
