Claims

[Scope of utility model registration request]

A capacitive type 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 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 is supported in the chamber in a cantilever shape by the block. a range beam, two slits provided in this range beam and formed in a closed curve shape with a part remaining concentrically, a range spring formed in the range beam with small rigidity by the slits, and a range spring formed in the range beam with a small rigidity; A moving part of the range beam surrounded by a spring, a rod connecting this moving part and the pressure receiving element, a fixed electrode attached to both sides of the range beam via an insulator, and this fixed electrode. A differential pressure transmitter comprising: a movable electrode arranged parallel to and facing the rod and attached to the rod via an insulator.
