Wireless Monitoring System

Long-range radio data acquisition systems (LS Series) constitute a new tool in the geotechnical and structural monitoring world.  

The LS systems help users:

  • Better manage their structure or project by providing data from the instruments of their choice;
  • Improve the protection of large structure by connecting large arrays of instruments;
  • Lower costs by connecting instruments over long distances without the need for cabling.
