Wireless Strain SenSpot™ sensors offer a breakthrough technology for real-time and long-term structural health monitoring. SenSpot™ strain gauge uses Resensys’s proprietary sensing,scheduling and ultra-low power synchronization technology.SenSpot™ is designed to operate maintenance-free for more than a decade. After installation, SenSpot™ does not need calibration,battery replacement, or any other maintenance during its entire service life.

Long- term and continuous monitoring of strain (stress)
Detecting short-lived and transient high-strain events, e.g., caused by fast moving trucks on highway bridges or by turbulence on airframes
Fatigue awareness, fatigue life analysis (remaining useful life estimation)
Fast, easy-to-install adhesive mount
Examples applications:
Highway bridges
Machines, cranes, etc.
Truck tests, bridge load rating
