SenSpot™ inclination/tilt uses Resensys's proprietary Active RF Technology. Resensys ART technology offers a high performance method for SenSpot™ Inclination/Tilt large-scale sensing, wireless synchronization, and ultra-energy efficient wireless communication. SenSpot™ is designed to operate maintenance-free for more than a decade. After installation, Sen-Spot™ does not need calibration, battery replacement, or any other maintenance for at least 10 years. Due to small size and lightweight, adhesive-mount 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 Resensys solution for integrity monitoring system, SenSpot™ inclination/tilt can be used to monitor smallest movements of structural components such as piers, decks, bearings on a highway bridge. In addition, SenSpot™ inclination/tilt monitors changes in these parameters 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.

Tilt SenSpot Tilt SenSpot comes in either self-adhesive or flange-mount form factors. The attachment of flange-mount SenSpot is done using four bolts. This option is mostly used for installation on concrete structure. The picture below shows a diagram for such a unit. All dimensions are in mm (inch). In order to install the SenSpot on metal surfaces, a piece plexi sheet is used as an intermediate. The SenSpot is screwed to the plexi sheet which provides a smooth surface for metal attachment using a double sided adhesive.
