Patent attributes
A gas pressure sensor 100 is disclosed as including a housing 10 to which a pressure is adapted to be introduced, a stem 20 communicating with the housing to admit the pressure thereto and having a diaphragm 22 deformable in response to the pressure, a sensor 24 associated with the diaphragm to produce an electric signal depending on a deformation of the diaphragm, and a substrate 30 that responds to the electric signal to generate an output signal that is outputted through a terminal 50. A chip capacitor 33 is connected between the terminal 50 and the substrate 30 and includes a first electrode 36, which admits a noise passing through the terminal 50 to be inputted to the substrate 30, and a second electrode 37 electrically connected to the housing 10, thereby enhancing improved resistance to noise.
