AAA640 MEMS Accelerometer
Acceleration sensor with 2 signal outputs in MEMS technology
About the AAA640 MEMS Accelerometer
The AAA640 Series of Solid State Accelerometers measure vector acceleration with high accuracy using an advanced micromachined (MEMS) silicon sensor incorporating a gas damping feature. Unlike fluid damped devices the gas damping employed is essentially independent of temperature. The transducer also incorporates positive mechanical stops confering excellent shock resistance. The accelerometer is also compensated for the effects of temperature on both sensitivity and zero.
Key features AAA640
- Essentially zero temperature coefficent of damping ratio
