Pressure sensor apparatus and pressure sensor housing

摘要

A pressure sensor apparatus and a pressure sensor housing are provided that are capable of preventing the occurrence of frozen moisture, swelling of a gel-like coating member and damage of a pressure sensor element (201) without accumulating moisture, oil, gasoline or the like on a protective wall (108) even when the pressure sensor apparatus is disposed obliquely. The protective wall (108) prevents entry of foreign matter into the pressure detection chamber (102), or a pressure sensor housing of the pressure sensor apparatus. The protective wall (108) has an inclined surface (108a) such that a second angle is acquired between a horizontal line and the inclined surface (108a) that slopes downward when the pressure sensor apparatus is disposed obliquely by a first angle with respect to the horizontal line.
