Abstract
Apparatus for condition monitoring the integrity of a rivet joint holding together sheets and of a structure includes a substantially fluid impervious pad for covering the heads of the rivets and an adjacent surface of the structure The pad has a first surface for placement over the rivets and the surface An inner portion of the surface is formed or otherwise configured to define a fluid flow region between the pad and the rivets /surface across which fluid can flow. The region is coupled to a constant vacuum source via a conduit and a series coupled high fluid flow impedance A transducer and display coupled in parallel across the impedance provides an indication of change in differential pressure across the high impedance which in turn provides an indication of the presence or development of a flaw in the rivets joint.
