Abstract : A new approach using quartz crystal microbalance (QCM) sensor to monitor oil viscosity on n line is developed. The measuring principle of quartz crystal microbalance sensor used in the viscosity measurement of oil is given. To satisfy for oil environment , the sensor detector and oscillator circuit is developed. The test result s show that the f requency shift s of sensor are linearly dependent on the square root of viscosity. The method of viscosity monitoring based on microbalance sensor is very sensi2 ble and can be used in on2line oil viscosity analysis.
Keywords : quartz crystal microbalance ; viscosity measurement ; oscillator ci rcuit
