| Abstract: | Using the phenomenon of magnetic induction a method for measuring the relative axial and radial displacements between reinforcing steel and concrete has been developed. For this measuring system a Hall sensor is glued to the surface of the reinforcing steel to receive the variable magnetic induction caused by a permanent magnet placed within the concrete. |
