Programmable Mems Shock And Vibration Sensors Simplify Industrial And Instrumentation System Monitoring

The programmable ADIS16240 impact sensor delivers superior power efficiency and user configurability in embedded applications while detecting and storing critical events for subsequent analysis. The programmable ADIS16220 digital vibration sensor provides designers with the capability to automatically capture profiles of subtle vibration shifts in machine performance and many other industrial applications that require wide-bandwidth sensing.

Analog Devices' new iSensor intelligent sensors enable designers to easily add high-performance shock and vibration sensing to a broader range of industrial and instrumentation applications at a fraction of the cost of previous monitors, said Bob Scannell, business development manager, iSensor intelligent sensor products, Analog Devices. By combining full programmability with performance, size, and power advantages, ADI's ADIS16240 and ADIS16220 can be adapted easily into many different operating scenarios to sense, measure, process, and store signals for either offline or real-time analysis with more accuracy and energy efficiency than previously possible.

ADIS16240 - Highly Accurate Impact Sensor Optimized for Low-Power Designs
The ADIS16240 is a fully integrated digital shock detection and capture system that combines ADI's iMEMS technology with an embedded signal processing solution, enabling designers to cost-effectively convert critical motion data into valuable system information in low-power applications such as condition monitoring, impact detection, security sensing and tamper detection. The device's low power triple-axis shock and impact sensor and recorder includes an integrated on-chip programmable event capture buffer, which monitors for user programmed shock thresholds and holds pre- and post-event data, time-stamp, temperature and voltage.

Programming features and data access are controlled from a standard SPI (serial peripheral interface) port, making the ADIS16240 compatible with many existing systems. Once implemented in the system, the device operates autonomously, capturing multiple events for later analysis or providing real-time indication of excessive shock environments.

The ADIS16240 consumes less than 1 milliamp in continuous sampling mode, making it ideal for use in portable or battery-powered security devices, remote safety monitors or products that monitor the condition of goods or shipments. With a usable bandwidth of up to 1.6 kHz, the ADIS16240 is significantly more capable of capturing critical shock events than previously available solutions.
