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.

Detect Transparent Colors with the ColorMax VIEW

ColorMax VIEW - EMX IndustriesThe ColorMax View sensor from EMX Industries, Inc., is a unique product which will open up a wide range of solutions and capabilities for your manufacturing and quality control processes.

With the ColorMax VIEW, you will be able to accurately detect and verify transparent or translucent color, the kind of which you will find on tinted materials, pharmaceutical or food and beverage packaging and containers, and more. It’s a great option for improving aesthetics and maintaining product uniformity, and even protecting from the damaging effects of light.

Detecting color in an opaque material is an easy process, by comparison, as little if any light passes through the material itself. This enables a sensor to simply shine a light directly on the target and “see” the color.

However, when you’re dealing with a transparent, translucent or tinted material, a standard sensor can’t detect or see that color because the clear target simply allows light to go through.

Luckily, we developed the ColorMax VIEW specifically for high-speed on-line color verification of translucent materials, combining our field-proven sensor technology with innovative hardware and setup.

Essentially, by utilizing a separate light source at the end of its cable, you can put the ColorMax VIEW in any position and pass the material through, allowing those colors to reach the sensor itself and then be accurately verified.

By establishing pass/fail criteria for color characteristics, you will be provided with real-time quality control while eliminating defects. With color variation of .5% and a 20 kHz switching frequency, you’ll be making use of the best specs in the industry.

Serial data output allows external systems to measure color and optimize the concentration of colorant, which improves efficiency and reduces cost, and external level monitoring is available through analog RGB output channels. Plus, the ColorMax VIEW is built to last with rugged construction and M30 housing to hold up to the demands of an industrial environment.

To learn more about the ColorMax VIEW and how it will be able to help you, call the EMX team today at 216.518.9888.



Color Sensors Make a Huge Difference in Quality Control

For most manufacturers, across a variety of industries and potential applications, the true importance of consistent and accurate color detection isn’t recognized until a problem occurs. Suddenly, mismatched parts and components end up in a final product, inconsistent results are allowed to persist unchecked, and ultimately, the slowdowns, costs and inefficiencies pile up.

The truth is that all color sensors aren’t created equally. Luckily, it’s never too late to upgrade to a versatile industry-leading solution such as the ColorMax-1000 series from EMX Industries, Inc.

The ColorMax-1000 is available in over a dozen different models, offering an unmatched set of specifications which will ensure a job well done. Choose spot size from 4 to 25 mm, operating range from a maximum of 50 to 150 mm, and up to 15 color channels which means you need fewer sensors, and you never need to reprogram when you change setups.

You’ll also find that the ColorMax-1000 is extremely fast and efficient, as much as five times faster sample speed, and it offers the highest resolution and repeatability specs in the industry.

Plus, we utilize sophisticated and innovative algorithms which ignore the presence of luster and ambient light. This means that no matter how the conditions or the environment of your facility may change – different degrees and sources of light at different times of the day, for instance – your results will remain consistent, verifiable and wholly accurate.

All of these features and capabilities make the ColorMax-1000 an innovative game changer for quality control purposes, with endless applications. Imagine you’re an automotive supplier needing to ensure that correct color shades on various small components are all in the right place at the right time — See our case study on this very issue here (PDF).
