Claims

[Scope of utility model registration request]

A movable electrode and a fixed electrode are disposed facing each other in an internal chamber formed in the main body, a sealing lid is fixed to the main body or a member fixed to the main body, and one end of each of the movable electrode and the fixed electrode is sealed with the sealing lid. the movable electrode and the fixed electrode are cantilever-supported by filling the inside of the sealing lid with glass; A pressure-receiving element is fixed so as to close the communicating through-hole, and the pressure-receiving element and the other end of the movable electrode are connected by a rod, and when the pressure-receiving element receives pressure, the above-mentioned movement occurs via the rod. In the pressure transducer device, the pressure is detected based on the capacitance between the movable electrode and the fixed electrode when the electrode is displaced, and the sealing lid is formed into a cylindrical shape, and one side of the sealing lid is A pressure transducer comprising a backing plate for receiving the glass in the opening of the pressure transducer.
