| 摘要 |
The invention relates to an impact sensor having an elastically deformable hose (6) and at least one pressure sensor (4). The pressure sensor (4) is arranged in a pressure sensor housing (2), wherein a tubular connecting piece (14) is provided on the pressure sensor housing (2) and the hose (6) is fixed to said tubular connecting piece in a pressure-tight manner. In the interior of the pressure sensor housing (2), a pressure feed duct (13) is formed between the tubular connecting piece (14) and the pressure sensor (4), wherein the pressure feed duct (13) is separated from the other housing internal space (11) by a separating means, for example a seal (5) and a wall (15). Between the pressure feed duct (13) and the other housing internal space (11), a first pressure compensating element (12) is provided, wherein the latter is preferably configured as an opening or a passage duct in the separating means (5, 15). Between the other housing internal space (11) and the environment, a second pressure compensating element (9) is provided, which is preferably configured as an airtight but elastically deformable diaphragm which, preferably together with the seal (5), is made as a soft component in a two-component injection molding. |
