MicroStrain Inc. has released the latest version of its Agile-Link wireless nodes that feature real-time streaming rates up to 4KHz. This is a significant increase in sample rate, which opens up many new applications for wireless sensor networks.

The Agile-Link nodes that support high-speed streaming rates are the G-Link wireless triaxial accelerometer node, the V-Link wireless voltage node and the SG-Link wireless strain gauge node. These nodes continue to offer flexibility with low-duty cycle mode and standalone data-logging capability.

These devices are suitable for condition-based monitoring of machinery for predictive maintenance; impact and crash testing, measuring torque; strain and load on rotating equipment; and vibration monitoring and modal analysis.

Product features include:

  • Simultaneous streaming of real-time, high-speed data from up to 16 nodes;

  • RF communications band: 2.4GHz direct sequence spread spectrum, IEEE 802.15.4 radio standard;

  • Wireless communications range: 70m line-of-sight with standard antennas or 300m line-of-sight with high-gain antennas;

  • Real-time streaming rates up to 4KHz;

  • Data-logging sample rates up to 2048Hz;

  • 2Mbyte flash memory stores up to 1,000,000 data points;

  • Internal Li-ion rechargeable battery and advanced energy-saving features; and

  • Open serial protocol enables users to develop high-speed applications in LabVIEW
