Micromachined
Servo Accelerometer Endevco Model MSA100A
The Endevco Model MSA100A Servo Accelerometer utilizes
a force rebalanced sensor that offers exceptional ruggedness,
high resolution, and low vibration rectification. Temperature
output and calibration coefficients are standard features
allowing for modeling to 3 mg accuracies.
The Model MSA100A is designed for inertial motion studies
in vehicles, tactical grade missile IMU's, flight tests
and tilt/angle measurements.
At the heart of the MSA100 is a three-layer micromachined
silicon sensor. The middle layer includes the proof mass
which, with applied acceleration, is electrostatically
rebalanced to a null position between the upper and lower
electrodes. This force rebalancing offers a wide bandwidth,
minimal non-linearity and excellent performance in high
shock and vibration environments. External resistors are
used to adjust full scale range from the standard +/-50
g's to lower g levels without affecting the accelerometer's
electronics. The MSA100A also has self-test capability
which moves the proof mass and outputs a proportional
signal.
The micromachined silicon sensor and hybrid electronics
are hermetically sealed for environmental protection in
a stainless steel case with an industry standard mounting
pattern. The Servo Accelerometer is also available with
a triangular mounting plate as a Model MSA110A.
