Abstract

PURPOSE: To provide a pressure measuring instrument which can be attached easily, is hardly affected by temperatures and magnetic fields, and can operate accurately by providing a chamfered section, etc., on the outer periphery of a cylindrical body having a center passage for passing a pressure medium within the extent where the pressure measuring instrument is provided. CONSTITUTION: A plate 12 is provided in parallel with a chamfered section 11 at a specific interval. The plate 12 is composed of a metallic layer vapor- deposited on a ceramic body 13. Since a thin wall section A is produced on one side of the wall of a pipe by the chamfered section 11, the thin wall section A is slightly bent and the capacitance impedance of a capacitor changes in proportional to the pressure of a high-pressure pressure medium when the medium flows through the center hole 15 of the pipe formed as a passage. The capacitance change of the capacitor which is generated by the slight bending of the section A can be evaluated by means of, for example, a high-frequency vibration circuit. Therefore, a pressure measuring device which can be attached easily, is hardly affected by temperatures and magnetic fields, and can precisely operate can be obtained.
