Claims

[Scope of utility model registration request]

A housing, a seal diaphragm provided on both sides of the housing to form first and second seal chambers, a back up nest provided in the housing opposite the seal diaphragm, and the housing. an internal cavity provided in the interior; a body provided in the internal cavity; one end supported by the body and the other end supported by the housing so as to support the body with a gap maintained in the internal cavity; a connected tube, a chamber provided in the body, a center diaphragm that divides the chamber into a first center chamber and a second center chamber, and a center diaphragm that divides the chamber into a first center chamber and a second center chamber; a first communication hole that communicates through the tube; a second communication hole that communicates between the second center chamber and the internal cavity;
A third communication hole that communicates the internal cavity and the second seal chamber, a differential pressure converter provided on the outside of the housing, and a differential pressure converter that converts the pressure in the first and second seal chambers, respectively. the first and second seal chambers, the first and second center chambers, the internal cavity, the first, second and third communication holes, and the conduction path. A differential pressure measuring device comprising two chambers each filled with an incompressible sealed liquid.
