SBI thickness gauges SHADOW
SBI's Inline thickness gauge SHADOW was developed for sheet extrusion (thermoforming sheet e.g.) up to 3,5 mm. Especially also for sheet which its properties must not be constant over the width (fillers, glass fibres, e.g.).
SHADOW utilises the principle of laser shadowing over a measurement roller, it is a direct measurement system (measures thickness like a micrometer screw gauge) not depending on sheet properties.
SBI's KAPA and SHADOW are designed also for retrofitting existing extrusion lines (the scanner can be installed vertical, horicontal or in every angle, even upside down would be possible).
