Meggitt Sensing Systems' Endevco model 7287

Meggitt Sensing Systems' Endevco model 7287 is a low mass piezoresistiveaccelerometer weighing less than one gram. Designed for the cost-effectivemeasurement of long duration transient shocks, such as those found in productand packaging drop testing, shipping container shock testing, jack hammer testingand high-g destructive testing applications.

With a measurement range of 2,000 g, 200 mVfull scale output and a high resonance frequency of more than 20,000 Hz, theEndevco model 7287 utilizes a MEMS sensing element incorporating integralmechanical stops and features a small, lightweight, easy-to-mount package forminimal mass loading of the test structure. This monolithic sensor designoffers ruggedness, stability and reliability with broad frequency response fromdc to 4,000 Hz at A plus or minus 5 percent, with non-linearity of <1 percent andruggedness to 10,000 g shock. The Endevco model 7287 has also minimum damping,thereby producing no phase shift over the useful frequency range.

The design of the Endevco model 7287 hasdrawn upon decades of proven experience in manufacturing these types of sensorsfor the automotive crash test market, with successful technology that has nowbeen carried over into the general test and measurement realm. As a result, themodel 7287 ensures critical data is recorded upon demand at very low cost.Units are available with adhesive mounting or integral bracket for screwmounting and are supplied with a strong PVC jacketed cable in standard lengths.
