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 for at least 10 years. Due to small size and lightweight, SenSpot sensors can be applied easily to as many critical spots on a structure as needed, with minimal installation effort.
As a part of the solution for integrity monitoring system, SenSpot inclination/tilt can be used to monitor the smallest movements of structural components such as piers, decks, bearings on a highway bridge. In addition, SenSpot inclination/tilt monitors changes in these quantities as the structure expands or contracts as a result of temperature variations. In addition to bridges, SenSpot inclination/tilt can be used in a variety of other structures. Examples include buildings, dams, etc.
- Bridge health monitoring
- Monitoring inclination of bridge piers
- Monitoring retaining wall movements
- Monitoring bridge bearing movements
- Scour critical bridge monitoring
- General structural integrity monitoring (buildings, dams, tunnels, etc.)
- Automation technology
- Aerospace engineering
- Monitoring of manufacturing process

The tilt sensors are built-in the SenSpot unit. They come by a pair of stainless-steel mounts that is especially designed for 2DHRT SenSpot and allows fine tuning of the mounting orientation in both Pitch and Roll directions. For proper installation of the device, please refer to 2DHRT user manual.
