Flexible strain gauge Wireless SenSpot™

resistanceresistivelinear

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. Strain Spikes Detection (Customizable) High sampling rate instant data transmission triggered by strain spikes: • A balance between power consumption and performance. • Perfect for detecting event and recording the waveform of a sudden strain change. • The triggering threshold is adjustable from 16 µStrain to 512 µStrain; the sampling rate can be changed from 10 ms to 200 ms Featured Applications • 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 ○ Airframes ○ Pipelines ○ Machines, cranes, etc. ○ Truck tests, bridge load rating Specs & Details • Long lifetime: minimum expected life without battery replacement 10 years • Lightweight： about 147 g (5.19 oz.) • Wireless transmitter: 120 g (4.23 oz.) • Cable (1ft): 10 g (0.35oz.) • Strain sensing element: 17 g (0.6 oz.)
