Claims

[Scope of utility model registration request]

A plotter-like body provided with a chamber inside, a measurement diaphragm that connects the chamber to first and second internal chambers, and a measuring diaphragm that covers each of the outer surfaces with the outer surface of the body serving as a back-up surface during overrange. a seal diaphragm provided in the body and forming first and second external chambers; a first communication hole communicating between the first internal chamber and the first external chamber; and a first communication hole connecting the second internal chamber and the first external chamber. a second communication hole that communicates with two external chambers; a first bellow that has a fixed end fixed to the body and communicates with the first communication hole; and a first bellow that incorporates the first bellow and whose fixed end is fixed to the body. A differential pressure measuring device, comprising a second bellows communicating with the second communication hole, so that measurement pressure on the high pressure side is applied to the seal diaphragm on the side of the first external chamber.
