Triaxial Accelerometers Support Aerospace Reliability Testing

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

Among the most critical of aerospace testing requirements is jet engine fuel control module reliability. 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. 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 mission critical batteries used in missiles, satellites and spacecraft, as well as those used as backup power sources, are also tested in this manner.

Featuring high sensitivities of 10 mV/g and 100 mV/g, with ±500 g and ±50 g measurement ranges, respectively, and with excellent amplitude and phase frequency response, the Endevco model 65 series incorporates Meggitt's own proprietary piezoelectric sensing elements for high-performance and stability, housed within a 10mm welded titanium cube with interface via a robust 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 further available with 0.5 mV/g, 1 mV/g and 10 mV/g sensitivities and reliable operation to +175°C (+347°F), without requirement for a separate charge amplifier.

All Endevco model 65 series units are accompanied by a comprehensive five-year product warranty, with quantities available for immediate shipment under Meggitt's Endevco Guaranteed In Stock program. They are also available at specially discounted rates as part of R replacement sensors program. Embassy Global, LLC, PO Box 105, Orchard Park, NY 14127 United States
