Wireless Displacement / Crack Meter SenSpot™

Description

Resensys Wireless Displacement/Crackmeter SenSpot™ provides an easy to install, scalable solution for distributed structural integrity monitoring of cracks, expansion joints, and much more. 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 over a decade. Once installed, it does not require calibration, battery replacement, or any other maintenance throughout its entire service life. Due to its small size and light weight, the adhesive-mount wireless crack detection sensors can be easily applied to multiple critical spots on a structure with minimal installation effort. Wireless crack monitoring gauge sensors are ideal for monitoring the progression of existing cracks in a structure. The device features a sliding element that moves in response to structural displacement or crack growth.
