The Agile-Link wireless sensor nodes include G-Link wireless triaxial accelerometers, V-Link wireless voltage, and SG-Link wireless strain gages. They feature real-time streaming rates to 4 kHz along with a low-duty-cycle mode and stand-alone data-logging capability. The devices typically serve in monitoring of machines for predictive maintenance; impact and crash testing; measuring torque, strain, and load on rotating equipment; vibration monitoring, and modal analysis. The sensor nodes feature data-logging sample rates to 2,048 Hz, a 2-Mbyte Flash memory that stores up to 1,000,000 data points, and an internal lithium-ion rechargeable battery.
