Subminiature Accelerometers from Endevco
September 14, 2006
Model 71 Series subminiature SMT piezoresistive accelerometers from Endevco Corp., San Juan Capistrano, CA, are rugged, undamped, and offer sensitivities from 3–30 µV/g for shock measurements from 6000–60,000 g. The internal sensing system is micromachined from a single piece of silicon and includes the inertial mass and strain gauges arranged in an active 4-arm Wheatstone bridge circuit complete with an onchip zero balance network. Features include small size, low mass, resonant frequencies from 180–700 kHz, low output impedance, and high over-range. Applications include munitions fusing, kinetic impact testing, and high-shock component testing.
