Miniature triaxial accelerometers

  • 21-Jul-2010 02:21 EDT

Dytran Instruments’ 3363A miniature triaxial accelerometers for modal analysis testing are robust, laser-welded titanium units that include ceramic sensing elements coupled to ultralow-noise junction field-effect transistor electronics. The IEPE-type piezoelectric sensors have a low-end frequency response of -5% down to 0.3 Hz, and they offer good phase response at low frequencies. The devices come in sensitivities of 10 mV/g, 50 mV/g, and 100 mV/g. Applications include general triaxial vibration measurements; shaker control; squeak and rattle; and noise, vibration, and harshness.

Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
