Meggitt Sensing Systems, a Meggitt group division, has announced the global market launch of Endevco® model 7298, a hermetic triaxial variable capacitance accelerometer with integral digital temperature compensation, designed for highly accurate measurement of low-frequency events. Typical applications require the measurement of whole body motion in three mutually orthogonal directions immediately following a shock or in the presence of severe vibrational inputs. The stainless steel hermetic package utilizes an integral water resistant connector, and when combined with the optional Model 3907 cable assembly, allows for extended outdoor exposure.
Available in six different models, ranging from 2 to 100 g, the Endevco® model 7298 incorporates a patented variable capacitive sensing element (US patent numbers 4,574,327; 4,609,968; and 4,999,735), with gas damping and internal over-range stops, which enable the transducer to withstand high shock and acceleration loads. All sensing elements are manufactured in-house at Meggitt's own ISO9001 certified MEMS facility in Sunnyvale, California, USA. The 7298 has the lowest profile in the industry at 14.2mm high and at a lightweight 22 grams, has a minimal impact on the mass of the test object. It features a very broad standard excitation input range covering 6 to 45Vdc, operates across the full military temperature range of -55 to +125C, and is easy to install with a simple two screw mounting. Endevco® model 7298 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 the sensor to provide the highest level of total accuracy available. In addition, the Endevco® model 7298 is covered by a five-year comprehensive product warranty.
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 systems tests, railroad testing and train tilt control, centrifugal force, launch loading and acceleration, and short-term navigation.
