压电陶瓷盘式Pb(Zr,Ti)O3 (PZT)传感器的横向效应被新引入液体动力粘度的测量中。实验中使用换能器的基波谐振（75 kHz）和高次谐波谐振频率（195、310、424 kHz）。以水-甘油混合物（粘度ηL：3~490 mPas）和硅油（ηL：10~1000 mPas）为样品液体，测量换能器的谐振电阻Rr和谐振频移Δfr。从实验结果可以看出，1）谐振电阻Rr与ηL1/2呈线性关系，2）谐振频移Δfr在大于100 mPas的高粘度范围内不表现出线性关系。我们的方法成功地完成了以前从未探索过的75~424 kHz频率范围内的粘度测量。
Transversal effects of a piezoceramic disk-type Pb(Zr,Ti)O3 (PZT) transducer are newly introduced in the measurement of dynamic viscosity of liquid. The fundamental resonance (75 kHz) and the higher harmonic resonant frequencies (195, 310, 424 kHz) of the transducer are used in the experiments. The resonant resistance Rr and the resonant frequency shift Δfr of transducer are measured with a water-glycerin mixtures (viscosity ηL:3~490 mPas) and silicone oil (ηL:10 ~1000 mPas) as the sample liquids. From the experimental results, it is gathered that 1) the resonant resistance Rr has a linear relationship to ηL1/2, 2) the resonant frequency shift Δfr does not show a linearity in the high viscosity range larger than 100 mPas. The viscosity measurement in the frequency range of 75~424 kHz, which has not been explored previously, was successfully accomplished by our method.
