Abstract
A pressure sensor comprises a sensor housing, a diaphragm provided in the sensor housing, and a snubber insertable into the sensor housing. The sensor housing includes a coupler coupling with a pressure measurement target and a housing passage passing through the coupler and guiding a fluid that flows into the sensor housing from the pressure measurement target. The diaphragm is deformable by a pressure of the fluid that flows into the sensor housing from the pressure measurement target. The snubber is inserted into the sensor housing through the housing passage and fastens to the sensor housing in a state in which at least a portion of the sensor housing forming the housing passage is deformed. The snubber guides flow of the fluid and transmits the pressure of the fluid to the diaphragm.
