Wireless Tilt/Inclination SenSpot™

Description

Using Resensys’s high precision tilt SenSpot™ sensors (HRT), movement, settling, deformation and abnormal tilting of bridge piers are detected 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.

Resensys's medium-resolution tilt SenSpot™ sensors (MRT) can also be used for monitoring a bridge's 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. The 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^TM sensors, movement, settling, deformation and abnormal tilting of bridge piers are detected at an early stage. High precision tilt data helps calculate vertical/horizontal displacement of piers, pylons and spans.
