Meggitt Intros Triaxial Accelerometer
Triaxial variable capacitance accelerometer.
Irvine, CA — Meggitt Sensing Systems, a Meggitt group division, has launched 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 suitable 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 100g, the accelerometer 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 is packaged in 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 unit has a broad standard excitation input range covering 6 to 45VDC, operates across the full military temperature range of -55 to +125°C with integral digital temperature compensation, and is easy to install with simple two-screw mounting. In addition, 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, enabling it to provide the highest level of total accuracy available.
