Free Uv Sensor Application Handbook
The UVX 300 luminescence sensor was designed to effectively detect UV luminescent materials and markers. The UV light source in the UVX 300 is directed towards a target and the visible light is reflected from the target back to the UVX300. Since the UV luminescent materials and inks are invisible under a normal light spectrum it is possible to mark products and parts without affecting their appearance. Some materials such as wood, grease and glue may contain UV luminescent materials naturally and in other cases the UV pigment may be added to the marking process.
The UVX 300 is used in many industrial applications to sense the following:
Grease Oil Glue Labels Epoxies UV ink Varnish Wood Textiles UV Crayons Paper Adhesive Although some applications may be similar to color or contrast sensing the UVX 300 offers unmatched detection of UV florescent materials. There are also applications where the lack of luminescence is detected, for example a break in a seal.
UVX 300 Design and Features:
Long Range sensing capability Auto-teach and Manual functions Receiver gain and detection threshold display High Resolution Programmable Discrete and Analog Outputs
The UVX 300 was designed to meet several requirements. First, the UVX 300 had to have a long range and be easy to program. Second it had to have a quantative display so the user can see what the sensor is registering. Third the UVX 300 has to have exceptional resolution so it can effectively suppress the background on large targets and limit the detection to a contained area on small targets. Last, it had to provide all the output function variations in the same model to limit the number of models that have to be carried in stock.
Our design team achieved those requirements. The UVX range exceeds 300 mm. The programming is done by a teach function for the simple application or by a manual adjustment of every parameter. The two-digit display lets the user see the amount of reflectivity from the target, so no more guessing is needed. The variable UV light intensity and additional focusing lenses greatly enhance the resolution of the sensor. The UVX 300 automatically senses if the required output is PNP or NPN and the programming pushbutton toggles the output from NO to NC. In addition, analog output and optional serial programming input are provided.
