HNTB, an architecture, engineering, planning and construction firm relied on the CX1 structural response monitor to track temperature, wind and pier movement, as well as sustained environmental and manmade elements. The versatile, all-in-one device continuously mounted on the pier caps so engineers could monitor tilt data to identify any sudden movements or change in stability. The CX1 also measured acceleration data to capture any indications of potential fractures within the concrete piers.

[Efficiency Improvement - Maintenance]
Real-time status reports enable maintenance personnel to remotely diagnose the status of a device.
[Process Optimization - Real Time Asset Tracking]
The location of individuals and assets can be identified in near real-time.

Within just the first week of operation, SENSR technology identified deterioration and frozen bearings that were delivering forces to bridge piers.
