How does X-ray inspection work?
X-ray inspection systems pass high energy X-ray beams through material and the detecting result is displayed visually in image form on the HMI touchscreen display. The denser the material inspected, the darker the resulting image will be.
Contaminant results are determined by special algorithms that compare differing contrasts received from the detector.
What contaminants can be detected using X-ray inspection?
A&D excels at detecting metal, glass, stone, hard bone, and high-density plastics with our X-ray systems.
What contaminants cannot be detected?
X-ray inspection systems cannot generally detect wood, hair, insects, cartilage, and other low-density items. Given certain environments, though, some items may be detectable, so it is always best to submit the product in question for a full evaluation. Contact us to find out about what is possible in your application.
Can you detect metal contaminants in a metalized film package?
Yes. This is one primary advantage that X-ray systems offer over metal detection.
How can I be sure that a specific contaminant is detectable?
A&D offers a free sample request program. Simply send us the samples, and we will test and provide a report on our findings. Contact us to start your sample test.
Can false rejects occur in X-ray inspection?
Yes, and this is true of all areas of product inspection. To safeguard against false rejects, we have developed special algorithms that are applied during the initial product setup process. This ensures a low rate of false rejects which leads to more uptime and a faster rate of return on investment.
Besides detecting contaminants, what other inspections can the ProteX X-ray system perform?
The ProteX X-ray system is incredibly valuable to our customers because of the variety of checks it can perform, beyond just inspecting for the presence of metal. Our systems feature:
- Mass estimation (checkweigh function)
- Seal inspection
- Component verification
- Presence of inserts/oxidizer packets within a package
- A simple user interface to easily take advantage of all of these features
Are the systems safe for operators to use?
Absolutely. Our machines are designed to exceed all US and European radiation safety regulations
Are the products considered safe after traveling through the X-ray system?
Yes. The radiation dose applied to the product during inspection is considerably less than the maximum allowable permitted by the FDA.
What other safety measures are applied to your system?
We incorporate the use of various interlocks and photo sensors.
- If a safety interlock is tripped, the machine will visually show the operator on the HMI what is tripped and how to fix/reset the problem.
- The photo sensors are in place to prevent any body parts from entering the machine.
If any interlock or photo sensor is tripped X-ray will immediately stop radiating.
What about tube life?
Today’s tube manufactures typically allow for 5,000 to 10,000 hours of tube usage. However, the life of the tube also depends on several operational factors including how often the machine is cycled. It is not uncommon that tubes can also last much longer than the expected life set by the manufacturer.
Do I have to calibrate the machine?
No. Each time an inspection is initiated, the machine automatically calibrates.
However, belt cleanliness can impact performance, so please make sure that belt is routinely monitored for cleanliness.
Should I buy an X-Ray or a Metal Detector?
This heavily depends on what is trying to be accomplished and where the system will be located within a process line.
X-ray can detect everything that a metal detector can, but it also comes with a larger up-front investment. If you are deciding between the two technologies, the best thing to do is to evaluate your process and determine what likely contaminants have an opportunity to be introduced within your process, as this can often be the deciding factor.
Our team can help guide you through evaluating and implementing the right solution for your needs.
Our processing plant is limited on space, do I have room for an X-ray system?
A&D offers the most compact X-ray inspection system in its class, the ProteX. This allows minimal line changes, if any, to integrate the system to an existing line.
