SenSpot - Wireless Displacement / Crack Meter
Displacement / Crack Meter SenSpot provides an easy to install, scalable solution for distributed structural integrity monitoring. Resensys SenSpot technology offers a high performance method for 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, SenSpot does not need calibration, battery replacement, or any other maintenance during its entire service life. Due to small size and light weight, adhesive-mount SenSpot™ sensors can be applied easily to as many critical spots on a structure as needed, with minimal installation effort. Displacement / Crack Meter SenSpot™ can be used for measuring the progress of the existing cracks in a structure. This device has a sliding element which moves with displacement of structure or growth of a crack.
