The Wireless Tilt/InclinationSenSpot™ sensors offer advanced technology for precise monitoring of tilt and inclination. Utilizing Resensys proprietary sensing, scheduling, and ultra-low power synchronization technology, these wireless tilt sensors provide real-time data on movement, settling, deformation, and abnormal tilting of structural components. Designed to be maintenance-free for a decade, these sensors do not require calibration or battery replacement after installation. The high precision data from these wireless tilt sensors helps in calculating vertical and horizontal displacement of piers, pylons, and spans, ensuring early detection of potential issues.
As part of the Resensys integrity monitoring system, the Wireless Tilt/Inclination SenSpot™ can monitor the smallest movements of structural components such as piers, decks, and bearings on a highway bridge. Additionally, these wireless inclinometer sensors track changes due to temperature variations in bridges, buildings, dams, and other structures. They are ideal for monitoring the deflection, bending, and settling of piers and abutments with high precision, as well as changes in tilt caused by settling, deformation, or loading.

A wireless tilt sensor measures the angle or inclination of a structure relative to gravity. It is commonly used to monitor structural movement, deformation, and potential instability in bridges, buildings, towers, retaining walls, and other infrastructure.
A wireless tilt sensor uses an internal accelerometer or MEMS technology to detect changes in angle. When a structure tilts or shifts, the sensor measures the change in inclination and wirelessly transmits the data to a monitoring system for analysis.
A wireless inclinometer sensor is a device used to measure the tilt or angular movement of a structure. It monitors changes in inclination and transmits the data wirelessly to a monitoring system, helping engineers track structural movement and detect potential deformation or instability.
The wireless inclinometer SenSpot can be used to monitor foundation stability, settlement, and angular movement caused by scour, thermal, and geotechnical effects. The sensors can also be used to quickly assess structural integrity after major distress events such as earthquakes or floods.
In addition, wireless inclinometers can be used to monitor angular movement in structural elements such as rocker bearings and bridge hangers. Moreover, arrays of high-precision inclinometers can be used to monitor deflections and vertical displacement of bridge girders under thermal loads, as well as track changes in stiffness over the long term.
