GEO-Instruments met these challenges with its WMPBX system (W for Wireless) paired with its unique Lid Link® module.
The WMPBXs used fiberglass rods and groutable anchors, so it could be preassembled, coiled, and shipped to the site, ready to install. This minimized disruption on the busy streets.
The issue of power was addressed by the use of custom-configured, long-life battery packs, purpose-specific data loggers, and rugged, low-power displacement sensors.
These components, together with a radio module, were sealed in a waterproof, stainless steel cannister and installed below grade. This solved the protection issue.
Wireless data retrieval was made possible by the Lid Link® module, which is a traffic rated, flush mount antenna. A secure GEO-Instruments server retrieved readings from each WMPBX via the web, and forwarded them to the owner’s project data management system for review in near-real time.
