Abstract
A pressure sensor comprising a pressure sensing assembly 24 and a pressrue transmitting medium 26 disposed within a main body 20 a seal assembly 34,35,36 disposed between the pressure sensing assembly and the main body for sealing between them against said pressure transmitting medium while allowing an easy attachment and detachment of the pressure sensing assembly relative to the main body. The pressure sensing assembly may comprise a sensing element 27 for detecting pressure, a base plate 25 for sealingly supporting the pressure sensing element within the main body and a pressure transmitting pipe 26 for transmitting the pressure to be detected to the element, and an O-ring in contact with the pressure transmitting pipe. A filling passage 15 which may be closed by a plug screw 16 may be disposed in the main body for filling the detection cavity with the pressure transmitting medium.
