れる水晶振動子セルに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quartz oscillator cell used for measuring viscosity, density, adsorption amount or a change thereof in the field of physical chemical measurement such as fermentation industry, polymer chemical industry and environmental measurement.

る。2. Description of the Related Art Among physicochemical indices, a rotary viscometer has been mainly used as a conventional viscosity measurement method. The rotary viscometer is a device for obtaining a viscosity by rotating a cylindrical or conical metal rod in a sample liquid and obtaining a shear stress. The present inventors have also disclosed a viscosity measurement method using a quartz oscillator.

用いた場合には、容器内の試料に回転体を浸漬しなくて
はならないため、高圧処理が必要な容器内あるいは高圧
下で測定を行う場合には、回転体と応力測定部分との間
をシールすることが難しく測定には適さなかった。When a conventional rotary viscometer is used, the rotating body must be immersed in the sample in the container, so that the measurement is performed in a container requiring high-pressure treatment or under high pressure. When performing the above, it was difficult to seal between the rotating body and the stress measurement part, and it was not suitable for measurement.

変動が生じるという問題点があった。On the other hand, in the method using a crystal resonator newly developed in recent years, since the sensor and the measuring circuit are connected by an electric signal line, the measurement is performed in a container requiring high-pressure processing or under high pressure. Even in this case, it is easy to seal between the sensor and the measurement circuit. However, in the case where the two electrodes of the crystal unit are used insulated, seal the periphery of the crystal plate of the crystal unit so that only one side of the crystal unit is in contact with the measuring solution. It is necessary to construct a cover that has a space on one electrode side.However, in the presence of pressure, liquid or vapor may leak from the outside to the space inside the cell, in which case the liquid or vapor that has entered the inside may be leaked. There was a problem that the condensation caused a fluctuation in the baseline of the sensor.

A cover having a closed space was formed on the other electrode side, and a pressure adjusting means was provided in a part of the cover. Further, the closed space was filled with liquid.

It is possible to prevent the output from fluctuating due to carelessly entering the liquid.
