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 aluminum housing that mounts via two M3 screws.
The unit has a mass of 10g and packaged size of 1-inch by 0.5-inch by 0.44 inch. It is available in seven variants with measurement ranges from ±2g to ±200g. The outputs are either two analog ±4V differential; or 0.5 to 4.5 V single-ended outputs that vary with acceleration. At zero acceleration, output differential voltage is nominally 0 VDC (DC response).
SDI Model 2220 series modules can withstand shock inputs of up to 2000g and can reliably operate over a temperature range of –55°C to +125°C.
