Abstract
The pressure sensor comprises the diaphragm, an electrode body, a housing, an inlet pipe, and a thermal buffer member. The diaphragm includes a pressure receiving surface configured to receive a pressure of a measured target fluid. The electrode body includes an electrode surface facing a rear surface of the pressure receiving surface with a gap interposed therebetween. The housing supports the diaphragm so as to form a measuring chamber by surrounding the pressure receiving surface. The inlet pipe is coupled to the housing and configured to guide the measured target fluid into the measuring chamber. The thermal buffer member is disposed on the inlet pipe and has a predetermined heat capacity. Accordingly, the diaphragm is unlikely to bend due to a rapid temperature change in a fluid guiding pipe disposed a fluid line.
