Meggitt Sensing Systems - Endevco Model 7257AT.jpg

The Endevco model 7257AT piezoelectric accelerometer from Meggitt Sensing Systems is designed for vibration measurements on flight test vehicles, particularly ones that incorporate telemetry for data acquisition. The compact, hermetically sealed device offers the functions of both flight test accelerometer and airborne amplifier. It comes in six models, with choice of 10 mV/g or 100 mV/g sensitivity and upper-corner frequency ranges from 500 to 5000 Hz. The unit offers ±2.5 V full-scale output, biased at +2.5 V dc, which can be directly interfaced with various telemetry systems.

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.
