Claims

[Scope of utility model registration request]

a block-shaped casing, a seal diaphragm provided on the outer surface of the casing and forming a seal chamber, a cover covering the outer surface of the casing, and an internal space provided within the casing;
a main body provided in the internal cavity; a tube having one end connected to the main body and the other end connected to the casing so as to support the main body with a gap maintained in the internal cavity; and an interior of the main body. A room set up in
a measuring diaphragm which divides the chamber into a first and a second measuring chamber and also functions as a moving electrode; a fixed electrode provided on the chamber wall opposite the measuring diaphragm via an insulator; and the main body of the casing. an overrange diaphragm provided on an internal cavity wall opposite to the overrange chamber and forming an overrange chamber; a backup nest provided in the casing opposite to the overrange diaphragm; the seal chamber and the first measurement chamber; a communication hole that communicates with the second measurement chamber through the tube; a connection hole provided in the casing that communicates the seal chamber and the overrange chamber; and the first and second measurement chambers.
A differential pressure measuring device comprising a sealed liquid filled in each of three chambers consisting of a measurement chamber, the internal cavity, the overrange chamber, the seal chamber, the communication hole, and the connection hole. .
