MicroStrain's wireless sensor networks enable simultaneous, high-speed sensing and data acquisition from multiple wireless strain gauges, accelerometers, temperature, and millivolt inputs. The range of wireless sensing systems is ideal for both small scale applications requiring a few sensor nodes and large scale applications requiring hundreds of sensor nodes. OEM options are available for embedded applications.

Featuring complete strain gauge signal conditioning, embedded processing, wireless communications, and precision timekeeping, SG-Link® -mXRS wireless nodes operate within a fast, synchronized, scalable network of wireless sensor nodes located up to 1 km from our WSDA® -Base. SG-Link® -mXRS nodes include an internal rechargeable Li-Ion battery and measure strain, torque, load, pressure and magnetic fields through a connector to user-supplied bridge sensors.
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 SG-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.
Featuring up to 4 KHz sweep rates, combined with 2 Mbytes flash memory, these little nodes pack a lot of power in a small package. With every node in the wireless network assigned a unique 16 bit address, a single host transceiver can address thousands of multi-channel sensor clusters.
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.
