Contactless measurements of thickness for plastics

Both confocal chromatic and interferometric sensors work contact-free favoring (inline-) measuring during the production process with high-speed operations and material transportation. Precitec Optronik in Neu-Isenburg offers for both measuring technologies an extensive portfolio of optical CHRocodile-sensors, allowing distance and thickness measurements within a wide measuring range designed for many different materials

Measuring plastic foils

Interferometric measurement systems are capable of measuring multilayer foils in between a few micrometers up to the millimeter range. All layers are measured simultaneously

Even though it is possible to measure from just one side, inline measurements during the production process are relatively easy to implement. The needed probes are very compact, which facilitates the implementation of traversing production systems. The probes are orientated crosswise to the advance direction of the foil, allowing to measure its whole width. One of the greatest perks of the interferometric measuring method is the high tolerance of varying measuring distances. That is why the foil can waver around without compromising the outcome of the measurements.

Apparently, there are almost no boundaries for interferometric measurements in the plastics sector.

The optical probes needed for interferometric determinations are not only very compact but they can also be arranged at various customer-specific measuring distances. This allows low expense installations of inline measurement systems. Even in mass productions with varying measuring distances and high speed productions can be easily fitted with our systems.
