THE CONNECTED INFRASTRUCTURE SOLUTION

MONITORING HOW STRUCTURES EVOLVE

Loadsensing is a data acquisition and monitoring system
which combines state-of-the-art wireless monitoring and
advanced software tools. It is widely recognized as the leading
solution for connecting and monitoring infrastructures in
remote locations.

Loadsensing devices are battery-powered and equipped
with long-range, low-power wide area network (LPWA) radio
communications and are compatible with a wide range of
geotechnical sensors. The software suite is web-based and
facilitates real-time data capture and analytics. It is also
possible to set automatic alarms to make operations safer.

Mining and construction companies and operators of
bridges, tunnels, dams, railways and many other inaccessible
assets can now work with reliable data. Having access to
this information and real-time insights enables operators to
anticipate needs, manage their workforce, diminish risks,
and even prevent disasters.

HOW IT WORKS

Operational Intelligence
for Mines and Industrial Companies

Worldsensing is not only among the best in the world at
connecting distributed infrastructures with smart devices,
we also know how to extract intelligence from collected data
to transform operations. Our software solutions combine
location intelligence with infrastructure monitoring.
