DISPOSITIF DE CALIBRAGE D'UN CAPTEUR DE PRESSION, NOTAMMENT D'UN CAPTEUR DE PRESSION INFRASONORE |
| 摘要 |
The invention concerns a pressure sensor, in particular an infrasound pressure sensor. Said device comprises measuring means (4, 6, 8, 14) for applying to said sensor (2) a reference pressure which varies in time and whereof all the spectral components covering a predefined frequency range are simultaneously excited with a common amplitude and a null phase shift, or constant delay, relative to one another.
