Agile-Link™ Wireless Data Acquisition System
Wireless sensor and data acquisition system
|
|
|
Description
This system allows for simultaneous data collection from multiple sensing nodes,
including MicroStrain's G-Link®, V-Link®, and SG-Link® wireless sensors.
MicroStrain® announces the Agile-Link™ product family. Agile-Link™ is a
wireless data acquisition system capable of simultaneous, high-speed data acquisition,
for use with wireless strain gauges, accelerometers, temperature, and millivolt
level inputs.
|
Applications
Structural monitoring, smart structures and smart materials
Vibration and acoustic noise testing
Assembly line testing with "smart packaging"
Sports performance and sports medicine analysis
Distributed security and machine health monitoring networks

How it works
MicroStrain, Inc. has developed "frequency agile" sensor transceiver nodes and base
stations, which can use a wide range of RF communications frequencies through software
configuration. This technique, termed frequency division multiplexing (FDM), allows
multiple wireless sensing nodes to communicate simultaneously without RF interference
between them.
Test and measurement applications often require the combination of wireless strain
measurement systems to be used alongside hard-wired sensors, all connected to an
existing analog data acquisition system. In order to easily support these applications,
MicroStrain has released Agile-Link™ analog output base stations that collect
analog data from multi-channel Agile-Link™ sensor nodes and then reconstructs
the analog waveforms on the base station's outputs.
To facilitate the use of wireless strain gauges, MicroStrain® has released a PC based
Agile-Link™ software package for Windows 95/98/2000/XP machines. In addition,
a new Strain Wizard® plug-in for Agile-Link™ supports wireless automatic
offset balancing, wireless gain adjustment, and wireless shunt calibration. The
Strain Wizard® is important for stress analysis because it allows the end user
to convert from bits out to physical units of strain.
