NI Wi-Fi Structural Health Monitoring (SHM) System

Configure Page for: Print PDF Rich Text
  • IEEE 802.11 (Wi-Fi)-based network infrastructure for remote measurements
  • Stream data on each channel at more than 50 kS/s with 24 bits of resolution
  • Simplify remote monitoring with LabVIEW and direct sensor connectivity
  • Protect data with 128-bit AES encryption, the highest commercially available standard
  • Features four strain and four accelerometer input channels, expandable for additional measurements
Specifications (5) popup

The NI Wi-Fi Structural Health Monitoring (SHM) System is based on NI Wi-Fi data acquisition (DAQ) devices, which combine IEEE 802.11 wireless or Ethernet communication, direct sensor connectivity, and the flexibility of NI LabVIEW software for remote monitoring of electrical, physical, mechanical, and acoustical signals. With built-in signal conditioning and the highest commercially available network security, NI Wi-Fi DAQ devices stream data in real time for easy-to-use, high-performance remote measurements.

The NI Wi-Fi SHM System features four accelerometer and four strain input channels; however, the system is expandable for additional measurements. The accelerometer channels offer software-selectable IEPE signal conditioning, 24-bit resolution, 102 dB dynamic range, 51.2 kS/s maximum simultaneous sampling, and antialiasing filters. The strain channels provide 24-bit resolution, 50 kS/s maximum simultaneous sampling, programmable half- and full-bridge completion, 1000 Vrms transient isolation, and transducer electronic data sheet (TEDS) smart sensor compatibility. The system also offers mixed-measurement capability for temperature, voltage, and other variables.
