Este dispositivo de medição de espessura sem contato é para filmes e folhas com uma espessura total de até 3 mm.
Está equipado com tecnologia dupla para medir a espessura total e também a espessura da camada de barreira individual (por exemplo, EVOH, BVOH, Nylon).
Filmes e folhas plásticas de múltiplas camadas para embalagens de alimentos.
Filme/Chapa de Barreira (Medição de Camadas)
XRS thickness gauges are available in widths of up to 8 m
Ultra-precise thickness measuring with an accuracy of ≤ 0,2 µm
KAPA (for total thickness)
It is based on a non-contact, indirect thickness measurement principle. The capacitance between sensor and roller depends on dielectric of measured sheet and distance between sensor to roller. To eliminate the influence of distance-fluctuations between sensor to roller this distance is measured permanently with an eddy current sensor (located together with capacitive sensor in the same casing). According to this measured distance the result of capacitive sensor is corrected.
IR (for the EVOH layer)
It is based on a non-contact, transmission measurement principle. For the determination of the EVOH layer thickness, a wide infrared spectrum of the plastic is recorded and the resulting absorption of the EVOH polymer molecules is evaluated by using our modern analytic methods.
