Samenvatting
Applied Technology Associates, has developed a new magnetohydrodynamic angular motion sensor for measurement of ultralow angular motion on pointing and tracking platforms. The transducer developed for the Department of Transportation, MHD AMS model IETL- 001, or simply IETL, is a smaller, lighter version of the original MHD sensor with modifications which allow measurement of the high angular velocities incurred by the Anthropomorphic Test Device (ATD) heads in crash testing. The principle of operation, the physical and performance characteristics, and the ATD head application test results will be presented.
