The pressure sensor that air conditioning equipment used

The utility model provides a pressure sensor that air conditioning equipment used, includes one kind sensor device (1) for go out at least one pressure at an air conditioning equipment item fluid pipe (20) internal detection, have: one base (4), it has been set for one contact surface (5) and has hugged closely on wall (18) of fluid pipe (20) one side with overpressure resistant mode, one section extension (four to six-tenehs) that stretches into in fluid pipe (20), one pressure sensor (2) are used for turning into an electrical measurement value with pressure, hereon, extension (four to six-tenehs) has formed at least one and has shown that it has straight main line (19) for the wing part (four to six-tenehs) of wing section to there is the section bar side (7) of the symmetric distribution relevant with it, one section bar front end (8) and a section bar terminal (9), hereon, at least, be equipped with one entry (15) on each section bar side (7) to every entry (15) are all passed through pipeline under pressure (10) and are connected mutually with the mode of water conservancy diversion with pressure sensor (2).
