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.

HS-Link-MIL - Hardened Extended Range High Speed Wireless Node
Fast, small, and rugged, the new HS-Link™ 100KHz-MIL high speed wireless node delivers the versatile MicroStrain® wireless sensing platform to applications that require speed. With maximum sample rates up to 100 kHz, and support for most types of analog sensors, including accelerometers, strain gauges, load cells, & pressure sensors, the node includes full strain gauge conditioning and programmable offset. HS-Link™ -100 kHz-MIL is EMI/EMC qualified to MIL STD 461F and is designed to be used in the most hostile environments.
The node is designed to log data to internal memory and upload wireless data to a host computer once logging is complete. Data is collected during periodic, user definable sampling sessions, at rates up to 100 kHz. Burst data is temporarily stored in a sample buffer (125,000 data points) and is then transferred to non-volatile, internal flash memory.
The bi-directional RF communications link can trigger logging from 70 meters (up to 100 m possible), or request that stored data be transmitted to the host PC for data acquisition and analysis.
The node’s scalable system architecture and programmable sensor interface enables a large network of nodes to simultaneously store dynamic data.
When used in conjunction with the MicroStrain® WSDA® or WSDA® -MIL. A proprietary beaconing protocol synchronizes every node’s precision timekeeper and coordinates and receives data collected from all sensor nodes in the network.
