HS-Link® -100 KHz High Speed Wireless Node

Fast, small and rugged, 1 channel wireless sensor node with 100 KHz sampling rates.

Overview

Small rugged and fast, the HS-Link® -100 KHz High Speed Wireless Node features complete strain gauge conditioning, embedded signal processing, an internal rechargeable battery, precision timekeeping, and operates within a fast, synchronized, scalable network of wireless sensor nodes. The HS-Link® -100 KHz samples most types of analog sensors at rates up to 100 KHz including acceleration, vibration, strain, load cells, torque, pressure, magnetic field, and more. The node posesses 4 MB datalogging memory, up to 70 meters range from its computer host, and out-of-the-box software.

At the heart of MicroStrain® mXRS™ Wireless Sensor Networks is the WSDA® -Base, or WSDA® -1000 which use our exclusive beaconing protocols to synchronize precision timekeepers embedded within each sensor node in the network. The WSDA® also coordinates data collection from all sensor nodes. Users can easily program each node on the scalable network for simultaneous, periodic, or burst mode sampling with our Node Commander® software, which automatically configures network radio communications to maximize the aggregate sample rate.
