MEMS acceleration sensor for aerospace and industry
Silicon Designs has announced an industrial grade MEMS accelerometer.
The single-axis Model 2220 is a higher-performance version of the company’s existing 2210, combining an integrated nitrogen-damped calibrated accelerometer chip with low-impedance buffering. Each is contained in an epoxy-sealed anodised aluminium housing that mounts with two M3 screws. “Low mass [10g] and small size [25x25x8mm] help to minimise mass loading effects,” said the firm. There are seven models measurement options from +/-2 to +/-200grav (changing and constant). Output is either +/-4V (differential analogue) or 0.5 to 4.5V (single-ended analogue) with outputs that vary with acceleration. “Differential sensitivity ranges are from 2V/g for the +/-2grav module to 20mV/g for the +/-200grav module, with typical 1% cross-axis sensitivity,” said the firm.
