Abstract

PURPOSE:To enable highly precise detection with excellent reproducibility by detecting the internal pressure of a closed body wherein a quartz vibrator is sealed according to the change in the impedance of the quartz vibrator. CONSTITUTION:The quartz vibrator Q is fixed within a metal case A by means of supporting lines l, l. The metal case A is closely fitted to a bellows B, and the two members share an internal space R with each other through hole parts P made therein, respectively, while the space R is filled up with nitrogen gas. When the pressure to be detected is applied to the bellows B, it is transmitted to the quartz vibrator Q and the CI value of the quartz vibrator Q is changed in accordance with the pressure applied thereto. Therefore, the pressure can be detected by detecting the CI value of the quartz vibrator Q. In addition, since the CI value is not influenced by the change in temperature, the measurement with high precision is secured.
