Viscosity Sensor of a Phase Detection Type

传统的粘度计需要大量的样品液体来测量粘度。此外，高粘度的测量和处理也很麻烦。为了解决这些问题，我们使用了一种压电双晶片换能器，加工成三角形。它被用作两个单态体：一个用于驾驶，另一个用于检测。为此，研制了一种新型粘度计，该粘度计可以将粘性载荷作为两个单晶片之间的电相位差来检测。将矩形双晶片加工成三角形，提高了对粘度相位差的检测能力。这种相位差只在一般的矩形双晶片中略有出现。三角形构型是一项重要而新颖的改进。此外，通常使用共振频率作为该双晶片的驱动频率。然而，在本研究中使用的是相位特性稳定的非共振范围的频率。这也是一款原创的f…到目前为止获得的结果证实了使用200-500赫兹的频率测量低粘度。然后，特别使用低于双压片第一共振频率的100赫兹或更小的非共振频带来尝试高粘度测量。在本研究中，根据所使用的双压片长度的不同，相位差偶尔会出现下垂特征。我们花了很多时间来澄清这一现象。最后，问题解决了。澄清了其原因，改进了结果，并介绍了该装置实际使用的可能性。由于在实验中使用了相位差，因此可以使用低频率测量高粘度。此外，使用如此低的频率是粘度计的一个新特点。这种粘度计允许使用少量液体进行简单的实时测量。它可以测量非常高的粘度，而使用传统设备很难测量这些粘度。因此，它可以方便地用于生产管理目的，包括一般材料的基础研究和食品工业。较少

A conventional viscometer requires a large amount of specimen liquid for viscosity measurement. Furthermore, measurement and handling of high viscosity are troublesome. To solve these problems, we used a piezoelectric bimorph transducer, processed like a triangle. It was utilized as two unimorphs : one was used for driving, and the other was used for detection. A new original viscometer was thereby developed that detects the viscosity load as an electric phase difference between two unimorphs. The rectangular bimorph was processed into a triangle to heighten the detection of the phase difference for viscosity. The phase difference appears only slightly in a general rectangular bimorph. The triangular configuration is an important and novel improvement. Moreover, the resonance frequency is generally used as the drive frequency of this bimorph. However, the frequency of the non-resonance range which the phase characteristic was steady was used in this research. This is also an original f … More eature of this experiment.Results obtained to date confirm measurement of low viscosity using frequencies of 200-500 Hz. Then, a non-resonant frequency band of 100 Hz or less, which is lower than the first resonance frequency of the bimorph, is used especially to attempt high-viscosity measurements. In this study, drooping characteristics occasionally appeared for the phase difference according to the length of the bimorph used. We spent much time to clarify that phenomenon. Finally, the problem was solved. Clarification of its cause improved the results and introduced the possibility of the device's practical use. Because the phase difference was used in the experiments, it was possible to measure high viscosities using a low frequency. Moreover, the use of such a low frequency is a novel feature among viscometers. This viscometer allows easy measurements in real time using a small amount of liquid. It can measure very high viscosities that are troublesome to measure using conventional devices. Consequently, it can be utilized conveniently for manufacturing management purposes including basic research of materials in general and food industries. Less
