Triaxial accelerometer ASC AiSys® ECO 3321

MEMScapacitiveCAN Bus

Overview
The smart sensor system ASC AiSys® ECO 3321 acquires and analyses accelerations. Preconfigured FIR and IIR filters and feature-extraction algorithms run on board. The triaxial accelerometer uses MEMS capacitive technology, offers configurable ranges from ±2 g to ±40 g and supports sampling rates up to 4 kHz per axis. Integrated electronics provide 20-bit acquisition resolution.
