This non-contact thickness measuring device is for film and sheet up to a total thickness of 3 mm.
It is equipped with dual technology to measure total thicknesss and also the individual barrier layer thickness (example, EVOH, BVOH, Nylon).
Multi layer plastic films and sheet for food packaging.
Barrier Film/Sheet (Layer Measurement)
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.
