The Millmate Thickness Gauging system, based on the Pulsed Eddy Current technology, opens up new dimensions in metal foil and strip gauging. Weak magnetic fields are used for the measurement and the gauge is completely safe to use.
The technology is completely insensitive to anything in the measuring zone, except the metal strip. The gauge will therefore measure true strip thickness unaffected by coolant, dirt, steam, air temperature variations, etc.
Since the MTG is material-independent there is no need for alloy compensation and calibration.
Measurement can be done close to the rollgap, without removal of emulsion.
