Silicon Designs introduces low mass MEMS accelerometers
Silicon Designs has announced the global market introduction of the compact, low-mass Model 2220 Series accelerometer.
The single-axis SDI Model 2220 is a higher-performance version of the company's Model 2210, combining an integrated low-noise, nitrogen-damped, fully-calibrated MEMS VC accelerometer chip with high-drive, low-impedance buffering, each contained in an epoxy-sealed rugged anodized aluminium housing that mounts via two M3 screws.
This design is ideal for measuring acceleration within industrial and commercial environments, where low mass (10g) and small size (1 x 0.5 x 0.44 inch) help to minimise mass loading effects.
Available in seven models, with measurement ranges from ±2g to ±200g and a wide frequency response, the SDI Model 2220 series responds to both DC and AC acceleration, with either two analogue ±4V (differential); or 0.5 to 4.5V (single-ended) outputs that vary with acceleration.
At zero acceleration, output differential voltage is nominally 0VDC (DC response). Differential sensitivity ranges are from 2000mV/g for the ±2g module; to 20mV/g for the ±2000 g module, with typical 1 percent cross-axis sensitivity.
Onboard voltage regulation also minimises supply voltage variation effects. SDI Model 2220 series modules can withstand shock inputs of up to 2000 g and can reliably operate over a temperature range of "“550C to +1250C. Each module is serialised for traceability and is fully calibrated, says the company.
