Fatigue Crack Growth Monitoring

Watch Product Line

The WATCH line of products are long-term structural monitoring products that monitor critical areas of a structure for fatigue crack propagation and monitor the crack growth in these key areas 24 hours a day. The products are based on an electrochemical system that additionally slows corrosion and fatigue crack growth. This line, which includes FATIGUEWATCH and SIGNWATCH, alerts owners of new problems and allows them to watch existing issues with their structures in between inspections as well as during contract letting times and through their lives.


The FATIGUEWATCH system is for structures that require special attention, such as structures that exhibit cracking and need to wait for repairs or retrofits or replacement, high profile structures that have fatigue susceptible details, systems prone to impact, or difficult to access structures which have experienced past fatigue problems and are either remote or have very limited access. The system includes custom number of sensors for specific structures as well as a data acquisition unit and communications center to handle 24- hour/day monitoring.


The SIGNWATCH system is a kit specially designed to monitor fatigue damage on overhead sign structures and light standards. The kit includes 4 sets of sensor pairs and a data acquisition system to monitor fatigue around the base of the structures or at cantilevered sections on 24-hour basis. This system is in the final development/testing phase.

They're always doing construction on the roads, they should inspect the signs along with the bridges!
