Basic Principle
Linear differential transducers with rounded natural or synthetic diamond inserts contact the strip surface from above and below. The evaluation of the differential signal results in the strip thickness.
Specific devices of the gauge head (such as the unique rotational suspension, heater, cooling system, etc.) ensure that the transducers are always perpendicular to the material regardless of the strip conditions, such as waviness, vibrations etc., and that effects, such as the strip temperature etc., can be compensated.
The different strip dimensions, speeds and environments gauge designs adapted to them.
Gauge for medium and wide strip mills, highest measurement accuracy with thicknesses up to 22 mm
Gauge for narrow strip mills, highest measurement accuracy with thicknesses down to 0,01 mm
Gauge for slitting lines or tube welding lines, for example, very robust
Advantages
Absolute measurement of the strip thickness, independent of alloys, easy maintenance, inexpensive spare parts.
