Description 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...

Wireless transmitter is universal and it reads the analog measurement from the sensing element and transmits the data wirelessly to SeniMax. These units come in either self-adhesive or flange-mount form factors. Resensys LLC www.resensys.com TEL: 301-405-9108 Email:[email protected]
