Endevco Accelerometers Deployed in Aerospace Applications

By DE Editors

Meggitt Sensing Systems announced the successful application of its Endevco model 65 triaxial ISOTRON (IEPE-type) accelerometer series to support aerospace reliability testing.

In jet engine fuel control module reliability testing, each module must be fully tested for vibration on a shaker, simulating actual use conditions, as well as evaluated for continued performance with fuel flowing through the unit, according to Meggitt. For this type of requirement, Endevco model 65 series accelerometers installed on the modules simultaneously measure their reaction to controlled vibration inputs across three orthogonal axes. In addition, the batteries used in missiles, satellites and spacecraft, as well as those used as backup power sources, are also tested in this manner.

The Endevco model 65 series incorporates Meggitt’s own proprietary piezoelectric sensing elements, housed within a 10mm welded titanium cube with interface via a 4-pin Microtech connector. With a compact, lightweight footprint that weighs just five grams, the model 65 series allows a test engineer or technician to make triaxial acceleration and vibration measurements on lightweight structures and objects. Temporary petro-wax adhesive and a ten-foot cable assembly with BNC connectors are provided as standard accessories, with an optional mounting block also sold separately. An optional high-temperature version, the model 65HT, is also available.
