Claims

[Scope of utility model registration request]

A capacitor comprising a main body, a chamber provided inside the main body and filled with a sealing liquid, a through hole opening from the chamber to both sides of the main body, and a pressure receiving element attached to the main body and covering the through hole. The type differential pressure transmitter includes an insertion hole that communicates the chamber with the outside, a block made of a metal material that is inserted into the insertion hole and closes the insertion hole, and a block supported in the chamber in a cantilever shape. a moving part formed by a closed curved slit provided in the range beam and leaving a free end side, a range spring part provided surrounding the moving part, and the moving part. A rod connecting the pressure receiving element, an insulating film provided on at least both sides of the moving part of the range beam, a moving electrode provided on the insulating film of the moving part, and a rod facing parallel to the moving electrode. A differential pressure transmitter comprising: a fixed electrode disposed and attached to a stationary part of the range beam.
