Meggitt Introduces Endevco Triaxial, Variable Capacitance Accelerometer

Meggitt Sensing Systems announced the global market launch of the Endevco model 7298 triaxial, variable capacitance accelerometer designed for highly accurate measurement of low-frequency events. Typical applications require measurement of whole-body motion in three mutually orthogonal directions immediately following a shock or in the presence of severe vibrational inputs, the company says.

According to the company, the new device is ideal for use in aircraft flight and flutter testing, automotive rough road body motion studies, suspension system tests, railroad testing and train tilt control, centrifugal force, launch loading and acceleration, and short-term navigation.

Available in six models, ranging from 2 to 100 g, it incorporates a patented sensing element with gas damping and internal over-range stops, which enable the transducer to withstand high shock and acceleration loads. It also features a stainless steel, hermetically sealed package utilizing an integral water-resistant connector that, when combined with the optional model 3907 cable assembly, allows for extended outdoor exposure.

It is 14.2 mm high and weighs just 22 grams, so the impact on the mass of the test object is minimal. It offers +0.5 percent FSO typical non-linearity and hysteresis for most ranges, and +1 percent FSO maximum for both thermal sensitivity shift and thermal zero shift.
