SENSOR FOR DETECTING SURFACE CRACKS IN A COMPONENT OR STRUCTURE |
摘要 |
<p>A sensor for detecting surface cracks in a component or structure. A preferred embodiment of the device comprises a flat body portion with a central hole through which a main structural bolt passes. The body portion has a throughway providing fluid communication between an exterior port and a substantially hermetically-sealed area on the structural surface being monitored. A crack which develops in the monitored area surrounding the bolt hole will cause venting of the hermetically-sealed area, in turn causing a change in fluid pressure that can be detected and/or measured to warn of the presence of the crack.</p> |
