Low contrast or colour differences between printed marks and
objects, or uneven object surfaces (e.g. rough, mottled or printed surfaces), frequently prove problematic for conventional colour and contrast sensors. The evaluation of luminescent features offers a simple and reliable alternative in these cases, or when marks are intended to be invisible on a product.

Thus printed labels or the package inserts for medicines can be checked, chalk marks on wooden surfaces can be detected, and bottles can be positioned in the filling plant with the help of invisible printed marks. Other applications include checking the presence of oils with added luminescent materials, or monitoring glue application on paper.
With its three-range reception system, the FT 50 C-UV can evaluate luminescences over the entire spectral range of visible light – users can easily choose the desired RGB partial spectrum via teach-in. This differentiates the SensoPart solution from most of the UV sensors available on the market, which require appropriate filters to achieve this. The FT 50 C-UV can also distinguish between differing luminophores on the basis of the frequency of the emitted light.
The powerful sensor detects even minimal amounts of luminophores, and thus operates very reliably. Highly reflective surfaces or varying object distances, e.g. with fluttering objects such as paper or when there is a batch change, have no effect at all on proper function.
