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 connected at one end to the main body and connected to the casing at the other end so as to support the main body in the internal cavity; and a tube provided inside the main body. a measurement diaphragm that divides the chamber into a first and a second measurement chamber and also functions as a moving electrode; a fixed electrode provided on the chamber wall opposite the measurement diaphragm via an insulator; an overrange diaphragm provided on the outer surface of the main body and constituting an overrange chamber; a backup nest provided in the main body opposite to the overrange diaphragm; and the seal chamber and the first measurement chamber or the first measurement chamber. a communication hole that communicates with the two measurement chambers through the tube; a communication hole provided in the main body that communicates the communication hole and the overrange chamber; and the first and second measurement chambers and the internal space. and a sealed liquid filled in each of three chambers constituted by the overrange chamber, the seal chamber, the communication hole, and the connection hole.
