Abstract
Disclosed is a particle velocity gauge for measuring long term (over one lisecond duration) particle velocities in solids which are subjected to high-powered sources, such as high-explosive detonations. The gauge consists of a protective canister, external flexible cable-protection system, and rigid internal strain-isolation system. The protective canister is disc-shaped and consists of a circular bottom section with central cavity, and a removable cover with o-ring seal. The strain-isolation system consists of a rigid mounting plate atop a TEFLON bearing, and is affixed to the bottom of the central cavity. A commercial accelerometer is mounted on the rigid mounting-plate to monitor the acceleration of the canister. The gauge is capable of operating a medium normal stresses to 90,000 psi, and offers improvements in measurement fidelity over previous gauges because of the design of the internal rigid strain-isolation system, and because the invention's density, overall shape and external dimension along its measuring axis, and its flexible cable protection system allows it to follow the mediums motions more faithfully. The gauge is also more robust than most prior gauges.
