Constant Pass-line Distance Technology (CPD)

Reliable inspection for changing Pass-line

Constant Pass-Line distance technology is an add-on to the SURFACE MASTER that allows inspection at the coiler, often the only available inspection position. The sensor maintains a constant distance to the inspected surface during the entire winding or unwinding process. This is the only way to ensure reliable inspection with a changing diameter of the coil.
