Wireless Instrumentation and Monitoring - Resensys, small wireless sensors that make big differences
Home > Products > SenSpot™ > Wireless Tilt/Inclination SenSpot™
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.
SenSpot™ uses Resensys’s proprietary sensing, scheduling and ultra-low power syn-chronization 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.
