Differential pressure sensor |
摘要 |
A pressure sensor for use with a sea mine for detecting the presence of a passing vessel by sensing a change in ambient water pressure caused by the Bernoulli effect relating to hydrodynamic flow induced by the vessel's motion. The sensor emits a responsive signal which can be used alone, or with signals from other influence sensors (acoustic and magnetic), to determine when the sea mine shoud be exploded. The sensor provides for equal sensitivity independent of the ambient pressure of the water at various depths at which sea mines may be planted, and employs electrical filters to eliminate noise.
