Silicon Designs, Inc. (SDI) has introduced four triaxial variable capacitive accelerometer families designed for use in low-cost, integrated plug-and-play devices for commercial, industrial and test and measurement applications.
The microelectromechanical systems (MEMS) work best with applications where low noise and long-term stability are needed requirements, SDI says. The accelerometers offer consistent performance with a typical non-linearity of only 0.15% force per unit area and typical bias and scale factor temperature shifts are zero. Typical bias and scale factor calibration errors are under 0.5%.
SDI’s triaxial accelerometers continue to work after sustained exposures to high temperatures. Source: SDI The triaxial accelerometers are offered in standard exposure ranges and can continue to operate after sustained exposures of up to 1,000 g and with limited temperature exposures of more than 150° C or greater.
The MEMS devices include three orthogonally mounted, low-noise, single-axis accelerometers in one rugged, epoxy-sealed anodized aluminum case. They also feature onboard voltage regulation as well as an internal voltage that eliminates the need for precision power supplies.
