The measuring range starts from 120 mm up to 420 mm with an accuracy of +/- 0,05 mm. This measuring systems are available with tactile sensors for the direct usage at the installed mould in the caster machine. They are also available with high precision laser sensors for a more detailed inspection of the mould in the work shop.
