Silicon Designs, a designer and manufacturer of rugged industrial-grade microelectromechanical systems (MEMS) capacitive accelerometer chips and modules, has introduced a ±5 g model to its 2210 accelerometer series. 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 just 1 square inch. The accelerometers feature a simple four-wire connection and internal voltage regulator to minimize supply voltage variation effects. Units are relatively insensitive to temperature changes and feature quick, easy self-calibration. (http://www.silicondesigns.com).
