Accelerometer for shock testing

  • 11-Oct-2010 02:45 EDT

Meggitt Sensing Systems’ Endevco 7287 piezoresistive accelerometer weighs less than 1 g and can be used to measure long-duration transient shocks such as those found in product and packaging drop testing, shipping container shock testing, jack hammer testing, and high-g destructive testing applications. With a measurement range of 2000 g, 200-mV full-scale output, and a resonance frequency of more than 20,000 Hz, the device uses a microelectromechanical systems sensing element that incorporates integral mechanical stops and features a lightweight easy-to-mount package for minimal mass loading of test structures. This monolithic sensor design offers ruggedness, stability, and reliability with broad frequency response from dc to 4000 Hz at ±5%, with nonlinearity of <1% and ruggedness to 10,000 g shock.

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.
