MEMS acceleration sensor for aerospace and industry
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.
On-board voltage regulation is included.
Shock survival is to 2000grav and operation os from -55 to +125°C.
Each module is serialised for traceability.
“Combined low mass, small size, and low-impedance make the series ideal for flight test, aircraft flutter testing, vibration monitoring and analysis, robotics, biomechanics, automotive RLDA, machinery and equipment control, modal analysis, crash testing, and general in-laboratory applications,” claimed the firm.
