Using Luminescence Sensors to Detect UV Crayons and Chalk Marks

UVX Luminescence Sensor - EMX Inc.Luminescence sensors are a reliable and efficient choice compared to vision systems when utilized in applications where individual visual assessments must be made.

A wonderful example of this is within the lumber industry. However, this can be deployed successfully in multiple environments including, to name a few examples, road marking, the steel industry, contract and construction work, paper mills, plumbers and electricians, and even artists looking to place invisible placeholders or guides for themselves.

In the case of lumber, the material is graded by an individual and defects are marked in order to be quickly chopped out or removed. A person is in charge of marking those defects, and then a sensor reads the mark, and the machine knows where to make the necessary cut with the saw.

A vision system, however, will encounter difficulties in making accurate detection’s due to patterns in the wood and other natural complexities which don’t match the uniformity you’d found in a processed material.

On the other hand, UV light is very insensitive to everything else that may be going on. A luminescence sensor looking for a UV target on lumber won’t be affected by the knots in the wood, the lightness or darkness of its surroundings, and so forth.

It’s only looking at the UV target, and doesn’t respond to anything else would offer interference. Therefore, UV crayon or chalk readable by a luminescence sensor is an ideal option in such an instance.

Another advantage this provides is that with greater accuracy, the sensor itself can be placed at a farther distance from the machinery. This is beneficial in the harsh environment of a lumber mill and will serve to protect the sensor itself.

The UVX luminescence sensor from EMX Industries is an industry-leading choice for such applications. It efficiently and consistently will detect its UV target, improving all-around results.

It can also be tied into existing programs which, for instance, optimize how and where to make cuts in order to optimize and maximize the output from a flawed piece of lumber.

The UVX is a versatile and feature-rich choice offering a digital display, numerous settings and adjustments for the utmost in fine-tuning capabilities, and much more. There are nine different models to choose from, ensuring that the specifications you’re looking for will be met exactly.

How Invisible Ink Helps Packaging and Security Applications

Invisible Ink UVX Luminescense SensorInvisible inks which are detectable by UV sensors have numerous applications. Two areas in which they have continued to grow more widely utilized and depended upon are packaging and security. In either instance, a reliable, industry-leading sensor such as the UVX luminescence sensor from EMX Industries will provide a perfect match.

Various forms of packaging materials will by necessity have registration marks to determine orientation and/or correct assembly. Of course, a visible mark on the packaging itself isn’t aesthetically suitable for consumer products. To solve this problem, UV marks and targets which are invisible to the naked eye can be utilized.

For instance, an invisible UV bar or mark could be printed every 10 or 12 inches to cut a clear film in the perfect length from a much larger spool. When your machine sees the UV mark, it instantaneously knows where to cut or slice that material, and completes that operation.

This provides a quicker and more consistent option than a gauge based upon the speed of how fast that material is moving. In the aforementioned scenario, the film unwinding from that spool will encounter numerous variables and complexities which changes its speed, such as nearing the end of the spool itself. This leads to an inefficient system where inaccurate readings are being made, and as a result, inaccurate processes are being conducted by the automated system.

In addition to packaging, invisible ink has also fantastic capabilities for security. Everything from dollar bills to credit cards today have various counterfeiting and security measures, often including UV inks and markers. Even a product such as expensive imported perfumes may have UV security ink on the packaging itself in order to protect against counterfeits and rip-off products.

In these cases, it’s easy to quickly determine whether or not a product is legitimate, without having any visible marks which could themselves be copied if they were visible, or would otherwise be aesthetically unpleasing as mentioned above.

With the family of UVX luminescence sensors from EMX Inc., you’ll be able to quickly, securely and consistently detect invisible ink for either packaging or security applications.

When efficiency and accuracy are vital for your specific application, the UVX luminescence sensor is an intelligent choice. For more information, to see the UVX in action, or to receive a pricing quote, call us at 216.518.9888 today to get started.

How Background Suppression Helps You Distinguish Between UV Targets and Optical Brightness

Digital Display on UVX Luminescense SensorThe 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.

The Importance of Visual Feedback and Calibration for a Luminescence Sensor

UVX - 100 & 300 Luminescence SensorsHaving easy to understand visual feedback and digital displays, and as a result, an array of fine-tuning and calibration capabilities, is an essential component to any high quality luminescence sensor. The problem is that many of the luminescence sensors on the market don’t offer this kind of display which can make a world of difference in terms of usability, as well as production quality and efficiency.

Luckily, the UVX family of luminescence sensors from EMX, Inc. is the industry leader in this department, offering a simple two-digit digital display ranging from 0 to 50 or 0 to 99 depending on the specific model. This offers instant visual feedback telling you how strong the signal is, and how close it is to being a match or not.

The way the UVX sensors work is that they project UV light onto the luminescent material. The light returned back to the sensor provides that two-digit value, which is an indication of the signal strength.

This allows you to make a simple decision on where to set a threshold for your readings and determine whether you’re hitting that target. As a basic guideline, many users end up setting a threshold at about halfway between the full reading received when viewing the correct luminescent material.

In addition to being able to set the threshold level, there are other settings which offer further control, including light source intensity. Thanks to a combination of that digital display, and an easy to work with menu structure, the full range of user selectable functions can be tweaked and set.

With the UVX, you’ll also be able to analyze and compare a variety of samples, some of which may be brighter or respond better to UV light than others. Other sensors don’t offer this functionality.

The UVX sensor works reliably and swiftly in automated situations, and ultimately, it’s a product which has more features and overall capabilities than many sensors from the competition.
