Differential pressure gauge with improved signal-to-noise ratio suppression

Differential pressure gauge with improved signal-to-noise ratio suppression

A differential pressure gauge of the invention contains: a diaphragm layer disposed between first and second parts; and a wall between a first region on a pressure-receiving portion side and a second region on a first through-hole side within a second pressure chamber. The diaphragm layer covers the...

description A differential pressure gauge of the invention contains: a diaphragm layer disposed between first and second parts; and a wall between a first region on a pressure-receiving portion side and a second region on a first through-hole side within a second pressure chamber. The diaphragm layer covers the pressure-receiving portion over a first pressure chamber and has the first through-hole with one end disposed in the second pressure chamber away from the pressure-receiving portion. The wall is disposed with gaps formed from inner walls of the second pressure chamber. The first pressure chamber is formed through the first part, the second pressure chamber has an opening facing the diaphragm layer, the first part has a second through-hole continuing to the first through-hole, and a base has a third through-hole with one end disposed in the first pressure chamber and a fourth through-hole continuing to the second through-hole.
