  • Lighting Strike Test Results
    As the application of composite aero structures has increased, the effect of lightning strike damage and the structural tolerance necessary to absorb this damage has required further test investigation. To enhance the damage tolerance capability of composite sandwich structures used for commercial
  • Industrial encoder integrates bearing and sensor functions
    resist corrosion in washdown, steam cleaning, and contaminated environments. The units work on the principle of the Hall effect. Hall sensors are solid-state powered devices that provide an output signal proportional to the strength of a nearby magnetic field. A magnetic pulser ring with alternating
