Accelerometer with digital temp compensation

Meggitt Sensing Systems has announced the global market launch of Endevco® model 7290E, a high-precision variable capacitance accelerometer with integral digital temperature compensation, designed for accurate measurement of low-frequency events and offering best-in-class thermal zero shift and sensitivity shift performance.

Available in seven different models, ranging from 2 to 150 g, the model 7290E 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. Available in a wide range of excitation voltages and choice of either differential or single ended output, as well as cable length, Endevco® model 7290E offers +0.2% FSO typical non-linearity and hysteresis for most ranges, with superior frequency response, enabling the sensor to provide the highest level of measurement accuracy available on the market today, In addition, the Endevco® model 7290E is covered by a five-year comprehensive product warranty.

With its exceptional bandwidth, precision accuracy and high shock survivability, the Endevco® model 7290E 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. Recommended accessories for use with model 7290E include Endevco® model 136 signal conditioner and the model 7990 triaxial mounting block.

Endevco are exhibiting at Britain's leading instrumentation event Advanced Manufacturing UK in April.
