MEMS Capacitive Sensing Modules?

MEMS Capacitive Sensing Modules?

Silicon Designs Inc.'s model A2260 is a high-precision accelerometer, expressly tailored for zero-to-medium frequency applications. It offers integral amplification and high-drive, low impedance buffering for precision measurements. The accelerometer produces two analog voltage outputs and features a four-wire connection, supporting both single ended and differential modes. Signal outputs are fully differential about a 2.5V common mode voltage. Sensitivity is independent from the supply voltage of +8 to +32V. At zero acceleration, the output differential voltage is nominally 0V dc; at full scale acceleration, the output differential voltage is plus or minus 4V dc. The sensors feature on-board voltage regulation and an internal voltage reference which eliminates precision power supply requirements. The sensor is relatively insensitive to temperature changes and thermal gradients. Self-calibration is quick and easy. Within standard range (2 to 400 g), most accelerometers continue to operate after sustained exposures of up to 10K g shock and with limited exposure to temperatures above +200C. Each sensor is made to be virtually identical, allowing users to swap out modules with minimal modifications.

Model A2260 was designed to meet a variety of automotive R&D, crash test and vehicle dynamics testing requirements such as NVH, drivetrain and powertrain testing, vehicle suspension and handling, crash event detection and airbag performance assessments.
