Variable-capacitance accelerometer

  • 05-Apr-2010 08:43 EDT

The Endevco model 7290E from Meggitt Sensing Systems is a high-precision variable-capacitance accelerometer with integral digital temperature compensation that enables accurate measurement of low-frequency events and excels in thermal zero shift and sensitivity shift performance. It comes in seven models ranging from 2 to 150 g. The device incorporates a variable-capacitive sensing element with gas damping and internal over-range stops that enable the transducer to withstand high shock and acceleration loads. Applications include aircraft flight and flutter testing, centrifugal force, and launch loading and acceleration.

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.
