Silicon Designs Introduces New MEMS Capacitive Accelerometer Modules

By DE Editors

Silicon Designs announced the introduction of a ±5 g MEMs Capacitive Accelerometer Module to its 2011 2210 series.

Designed to support a variety of lower frequency aerospace, automotive,  defense, energy, industrial, and general test and measurement requirements, the low-noise, single-axis model 2210-005 accelerometer module incorporates high-quality MEMS capacitive sensing elements. Sensing elements are packaged within a compact, lightweight anodized epoxy sealed aluminum housing, occupying a total footprint of one square inch. The accelerometers feature a simple four-wire connection and internal voltage regulator to minimize supply voltage variation effects. The units feature high-drive, low-impedance buffering to support low-frequency acceleration measurement requirements from 0 (DC)  to 400 Hz.

The module produces two analog voltage outputs which vary with acceleration. Users have the choice of employing either single-ended or differential output, which doubles the sensitivity over single-ended output to 800 mV/g. The sensitive axis is perpendicular to the bottom of the package, with positive acceleration defined as a force pushing on the bottom of the package.  The signal outputs are fully differential about a common mode voltage of approximately 2.5 volts. The output scale factor is independent from the supply voltage of +9 to +32 volts. At zero acceleration, the output differential voltage is nominally 0 volts DC; at ±full scale acceleration, the output differential voltage is ±4 volts DC.
