The everyday materials you’re using in your production line could actually be sabotaging your UV sensors. That is, of course, if you’re not using one of the feature-rich UVX luminescence sensors from EMX Industries, which offers unique background suppression capabilities that tackles this problem quickly and easily.
For example, we have worked with a customer who was applying adhesives to their envelopes, and needed to detect the presence of that adhesive glue on the envelope paper. However, there was a great deal of difficulty and frustration with this, because the optical brightness of the white envelope paper essentially blinded out the UV sensor, making it near impossible to detect the UV tracer in the adhesive.
Bright white paper or other bright materials can cause this type of problem, as can certain environmental factors. For instance, the brightly shining lights used in offices and certain industrial settings can also “blind” some luminescence sensors in this way.
In the above case, the paper itself was simply stronger in the typical blue spectrum of light used by UV sensors to detect their targets. The product couldn’t be changed, so instead, a solution needed to be developed to provide accurate readings.
With the UVX sensor, we were able to work around this challenge thanks to a special filter which can be utilized in combination with the sensor itself. The filter suppresses the range of blue light, which is where your background fluorescence is found.
This then allows weaker signals coming from the green and/or yellow spectrums to be read and analyzed. By changing to a tracer readable in that green-yellow spectrum, instead of blue, the issue of that background fluorescence is avoided entirely.
There are many potential applications which could face a similar challenge, and you’ll only find the results you’re seeking from the industry-leading UVX luminescence sensors. When you combine this type of capability with the rest of the features of the UVX, including the digital display and various adjustment settings, it’s easy to see that this is your top choice for reliability, efficiency and quality.
