Abstract
In a pressure sensor, a metallic pressure introducing pipe is fit into the pressure receiving inlet formed in a metallic housing and fixed there by welding. The housing has a flange portion in its upper portion, and the flange portion is fixed to the outer wall of a tank which is an object to be measured so that the pressure sensor body is located inside the tank. A porous filter made of fluoroplastics is arranged adjacently to the atmospheric pressure introducing inlet. An adhesive tape which is removable is attached to the atmospheric pressure introducing inlet. The pressure sensor can realize stabilized maintenance and highly reliable airtightness for a sensor element, less limitation to sensor layout design in a small space and also can surely introduce air with no drop of water and dust into the sensor.
