DYNA Grip^® Stay Cable Systems

This system has been developed to measure or monitor forces within single strands of a stay cable during the construction progress as well as during the entire service life.

Functional Principle

• The permeability of steel to a magnetic field changes with the stress level in the steel
• By measuring the change in a magnetic field, the magnitude of the stress in the steel element is obtained
• Data is gathered and elected by special system components
• Data can be handled using a conventional computer
