Abstract: <P>PROBLEM TO BE SOLVED: To make a measuring cell for quartz resonator usable also at a high- temperature and high-pressure specimen.  <P>SOLUTION: The measuring cell 20 for quartz resonator is constituted by watertightly attaching a quartz resonator 31 to an opening 23a in a casing having an airtight space 23. A pressure regulator 40 composed of a double acting cylinder is installed additionally at the measuring cell 20, and a pressure of the airtight space and a pressure of the specimen are adjusted to be an equilibrium. Thereby, a high-pressure specimen or a specimen having a changing pressure is measured. Since there is no pressure difference between the surface and the back of the quartz resonator 31, the quartz resonator 31 can be made thin, and a measurement accuracy of the measuring cell 20 is enhanced. The inside of the airtight space 23 is set to a constant pressure. When there is the pressure difference between the surface and the back of the quartz resonator 31, its measured value is numerically corrected on the basis of a correlation between itself and a pressure change. When a detection circuit 30 connected to the quartz resonator 31 is installed outside the casing, the high-temperature specimen can be measured. When the detection circuit is installed inside the casing, the measurement accuracy can be increased.  <P>COPYRIGHT: (C)2004,JPO
