Potential Probe Measuring Technology

Monitoring of faults for growth

Does the detection of a defect, a fault or an incipient crack mean the "end of the road" for a structural component? In many cases, continued operation is technically justifiable, even when the fault is inaccessible, such as on the inside of a pipe for example.

Safe continued operation
Using the potential probe method, the structural component is constantly monitored in operation to see if the fault continues to expand. The potential method offers a number of practical advantages and makes a significant contribution to plant safety.
Since 1997 there have been concrete examples of use at home and abroad, in particular in powerstations.

Applications

• Monitoring of faults in respect of crack growth
• Monitoring of faults on the inside
• Monitoring of faults on the outside
• High resolution of the growth in the fault
• Quantitative determination of the growth

Advantages

• Continued operation of faulty structural components (pipe or tank)
• Continuous monitoring in operation- Cost benefits
• In nuclear power stations: reduction in radiation exposure
