SG-Link® -mXRS? Wireless Strain Node

Product catalog summary

Features & Benefits:

Supports hundreds of simultaneous sampling wireless sensor nodes.
Node-to-node synchronization of +/- 32 microseconds.
Ultra-stable on-board precision timing reference of +/- 3 ppm over industrial temperature range.
Programmable communication range from 70m to 2,000m.

Applications:

Wireless flight testing of aircraft.
Condition-based monitoring of machines.
Health monitoring of structures and vehicles.
Smart structures and materials.
Experimental test and measurement.
Robotics and machine automation.
Vibration and acoustic noise testing.
Sports performance and sports medicine analysis.
Distributed security networks.

System Overview:

The mXRS™ system, centered around the WSDA®-Base, uses exclusive beaconing protocols to synchronize precision timekeepers within each sensor node. The WSDA®-Base coordinates data collection from all sensor nodes, including SG-LINK-mXRS, allowing for simultaneous, periodic, or burst mode sampling.

Introduction:

SG-Link®-mXRS wireless nodes feature complete strain gauge signal conditioning, embedded processing, wireless communications, and precision timekeeping. They operate within a synchronized network of wireless sensor nodes up to 1 km from the WSDA®-Base. These nodes include an internal rechargeable Li-Ion battery and measure various parameters through a connector to user-supplied bridge sensors.

Catalog excerpts

Extended Range Synchronized Wireless Strain Node Data Sheet 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. Features & Benefits • Support for hundreds of simultaneous sampling wireless sensor nodes • Node to node synchronization of +/- 32 microseconds • Ultra-stable on-board precision timing reference of+/-3 ppm over industrial temperature range • programmable communication range from 70m to 2,000m • Wireless flight testing of aircraft • Condition-based monitoring of machines • Health monitoring of structures and vehicles • Smart structures and materials • Experimental test and measurement • Robotics and machine automation • Vibration and acoustic noise testing • Sports performance and sports medicine analysis • Distributed security networks System Overview 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.
