This article defines the next generation of smart vibration sensors, which contain wide-bandwidth MEMS sensors, a complete signal chain that produces spectral alarm information, applies spectral alarm definitions and communicates through an embedded-friendly interface for simple integration into factory-preferred data communication infrastructure (ethernet, RS-4xx, wireless, etc). Note that since this article was published, the ADIS16228 and ADIS16229 offer lower noise and wireless interfaces respectively. Enjoy!
