Endevco Model 7290E Variable capacitance accelerometer Features Description DC response Օ 2 to 150 g fuLL scale Motion, Low frequency, tilt Օ 10K g shock survivability Precision digital temperature compensation The Endevco® model 7290E Microtron® accelerometer family utilizes unique variable capacitance microsensors. The accelerometers are designed for measurement of relatively low level accelerations in aerospace and automotive environments. Typical applications require measurement of whole body motion immediately after the accelerometer is subjected to a shock motion, and in the presence of severe vibrational inputs. State-of-the-art digital temperature compensation electronics provide for precise compensation over a wide temperature range. Gas damping and internal overrange stops enable the anisotropically-etched silicon microsensors to withstand high shock and acceleration loads. The accelerometer is available with a choice of two power options. One option (R) allows for operation from 9.5 V to 18.0 V. The second option (U) allows for operation over a range of 12.5 V to 36 V. The 7290E provides both a differential and single ended output. The differential output has a range of ±2 V and is DC coupled. The single ended output is 0.5 V to 4.5 V with 2.5 V of bias voltage. Frequency response is controlled by the near-critically damped sensors. The use of gas damping results in very small thermally induced changes in frequency response.
