Meggitt Sensing Systems Introduces Endevco Triaxial, Variable Capacitance Accelerometer for High Accuracy in Low Frequency Measurements

Meggitt Sensing Systems, a Meggitt group division and leader in sensing and monitoring systems for extreme environments, has 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.

With its exceptional bandwidth, precision accuracy and high shock survivability, the Endevco model 7298 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, the Endevco model 7298 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.

With the lowest profile in the industry at 14.2mm high and light weight of 22 grams, the impact of the Endevco model 7298 on the mass of the test object is minimal. It has a very broad standard excitation input range covering 6 to 45Vdc, operates across the full military temperature range of -55 to +125C with integral digital temperature compensation, and is easy to install with simple two-screw mounting. In addition, it offers +0.5% FSO typical non-linearity and hysteresis for most ranges and +1% FSO maximum for both thermal sensitivity shift and thermal zero shift, enabling it to provide the highest level of total accuracy available.

All sensing elements are manufactured in-house at Meggitts own ISO9001-certified MEMS facility in Sunnyvale, California, USA. In addition, the Endevco model 7298 is covered by a five-year comprehensive product warranty.
