PROXIMITY SENSOR FOR AIRCRAFT, PROVIDED WITH A SPECIAL SEALED ASSEMBLY |
| 摘要 |
Sensor (1) comprising:
a casing (2) delimiting an internal volume (3) and having a passage (31) between this internal volume and a first external zone (Z1) external to the casing;a moving part (4) able to move inside the said internal volume (3);detection means (5) for detecting a movement of the said moving part (4) comprising a detection portion (51) extending in the passage (31), and having a groove (52) open to the outside of the detection portion (51), this groove (52) extending between the said first external zone (Z1) external to the casing and the said internal volume (3) internal to the casing.;The sensor (1) comprises first sealing means (14) positioned around the detection portion (51) inside the passage (31), these first sealing means (14) being arranged in such a way as to prevent fluid from passing between the internal volume (3) and the first external zone (Z1) via said groove (52). |

1. A sensor (1) comprising:
a casing (2) delimiting an internal volume (3) internal to the casing and having a passage (31) extending between this internal volume and a first external zone (Z1) external to the casing; a moving part (4) able to move inside the said internal volume (3) of the casing; detection means (5) for detecting a movement of the said moving part (4) with respect to the casing (2), these detection means (5) comprising a detection portion (51) extending in the passage (31), between the said first external zone (Z1) external to the casing and the said internal volume (3) internal to the casing, this detection portion (51) also having a groove (52) open to the outside of the detection portion (51), this groove (52) extending between the said first external zone (Z1) external to the casing and the said internal volume (3) internal to the casing, characterized in that it comprises first sealing means (14) positioned around the detection portion (51) and placed inside the passage (31), these first sealing means (14) being arranged in such a way as to prevent fluid from passing between the internal volume (3) and the first external zone (Z1) external to the casing (2) via said groove (52). |
