Stress and strain sensing are an integral part of most structural condition monitoring systems. Wireless Strain Gauge SenSpot™ sensors offer a breakthrough technology for real-time and long-term monitoring of structural integrity. SenSpot™ strain gauge sensors use Resensys proprietary sensing, scheduling, and ultra-low power synchronization technology. It is designed to operate maintenance-free for up to a decade. After installation, wireless strain gauge sensor SenSpots™ do not need calibration, battery replacement, or any other maintenance during its service life.
