SenSpot - Wireless Tilt/Inclination Sensors

Also, Resensys`s medium-resolution tilt SenSpot™ sensors (MRT) can be used for monitoring of bridge bearings and expansion joints.
‍
SenSpot™ 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. Tilt/Inclination SenSpot™ is A breakthrough tool for precise monitoring of tilt, inclination, settling, bending, deformation, and deflection. Using Resensys’s high precision tilt SenSpot™ sensors, movement, settling, deformation and abnormal tilting of bridge piers are detected at an early stage, before such issues become major problems or lead to safety compromise and/or road closure. High precision tilt data helps calculate vertical/horizontal displacement of piers, pylons and spans.
