Description
Combining triaxial accelerometers, embedded processing, wireless communications, and precision timekeeping, G-Link® -mXRS™ wireless nodes operate within a fast, synchronized, scalable network of wireless sensor nodes located up to 1 km from our WSDA® -Base. G-Link® -mXRS™ nodes include an internal rechargeable Li-Ion battery and measure accelerations, vibrations, and tilt angles with its embedded accelerometers.
At the heart of MicroStrain's extended range synchronized (mXRS™) system is the WSDA® -Base, which uses our exclusive beaconing protocols to synch precision timekeepers embedded within each sensor node in the network. The WSDA® -Base also coordinates data collection from all sensor nodes, including G-Link® -mXRS™. Users can easily program each node on the scalable network for simultaneous, periodic, or burst mode sampling with our Node Commander® software, which then automatically configures network radio communications to maximize the aggregate sample rate.Combining MEMS accelerometers with MicroStrain's award winning Micro Datalogging Transceiver systems, G-Link® is a high speed, triaxial accelerometer node, designed to operate as part of an integrated wireless sensor network system.
Featuring up to 4 KHz sweep rates, combined with 2 Mbytes of flash memory, these little nodes pack a lot of power in a small package. Every node in the wireless network is assigned a unique 16 bit address, so a single host transceiver can address thousands of multichannel sensor nodes.
The bi-directional RF communications link can trigger a sample to be logged from up to 2000 meters, or request real-time data to be transmitted to the host PC for data acquisition/analysis. The frequency agile system enables simultaneous real-time streaming from up to 16 nodes in the 2.4 GHz range.
Available in 2G or 10G range, these small, fast, wireless accelerometers can be used to monitor tilt and vibration in a wide range of machines and structures.
