Q. Can the ScanTrac detect metal contaminants in metal containers?
A. Yes. X-rays penetrate metal or glass containers and allow us to detect contaminants inside. We can inspect metal cans, glass jars, containers with metal foil closures or made of metal foil, and many more. Please see container with different contaminants.
Q. What is the minimum conveyor space required to install the ScanTrac?
A. Typically, the ScanTrac requires six feet (1.8 m) of linear conveyor space. Sometimes it can take as little as 40 inches (1 m).
Q. What is the minimum space required between containers? Do you require leadscrews or accelerating conveyors to provide minimum space between containers?
A. We do not require any spacing between containers; they can be inspected back-to-back. However, the containers should not be under backpressure - this would prevent proper ejection. We do not require any leadscrews or accelerating conveyors.
Q. What contaminants are detectable by the ScanTrac?
A. We cannot detect insects, wood, thin plastic film, hair, and other low-density items in can or jars. Some of those items may be detectable in cardboard or paper containers. We excel at detecting metal, glass, stone, rubber, and many high-density plastics in most containers. Please see container with different contaminants.
Q. What makes the ScanTrac the most accurate X-ray inspection system in the industry?
A. Our sophisticated image processing software utilizes algorithms based on neural network principles, the most advanced area of image processing. Until recently, it was not practical for use in fast, real-time systems that process up to 40 images per second due to computer performance limitations.
Q. What ejectors are best suited for the ScanTrac?
A. This depends on the containers, speeds, container spacing, etc. Peco Controls manufactures a complete line of ejectors for every need. All of our ejectors are available online Eject-Stop-Divide.com . If you are unsure which ejector is right for you application, use Eject-Stop-Divide.com's Automated Expert.
Q. X-ray inspection devices are fairly complicated computer systems. How can I operate and maintain one if I do not have engineers or even trained technicians on staff?
A. Not a problem. Our remote access link allows InspX engineers to be there virtually, so to speak. And we can be there virtually almost around the clock. Our engineering team in the UK picks up the watch when our California team is off duty. Our trained engineers can see the screens your operators see, and they can push all the buttons your operators can push. And if there is an equipment problem, our automated trouble reports will notify your maintenance people and/or Peco/Inspx team by e-mail. Built-in diagnostic tools identify the culprit; we even have built-in voltmeters and a six-channel automatic oscilloscope. We are prepared.
Q. Why does the ScanTrac console look like a Star Trek console?
A. The ScanTrac console is designed for washdown and is completely sealed. The U-shaped channel is used to cool the air inside. And it looks cool.
Q. How often do you need to stop production for calibration?
A. Never. The ScanTrac automatically calibrates itself without production stoppage. You wouldn't even notice it.
Q. Can the ScanTrac operate on variable speed conveyors?
A. Certainly. It will automatically adjust to the conveyor speed without any operator intervention, from crawl all the way to the maximum rated conveyor speed.
Q. It is known that X-ray inspection systems sometimes reject perfectly good containers. Is this true for the ScanTrac?
A. It is; however, what matters is the rate of such false rejects. In the inspection industry a false reject rate of one in 1,000 is often considered par for the course. The ScanTrac false reject rate is well below one in 20,000 - a 20:1 improvement, and often is below one in 100,000. This is a very important consideration - it costs time and a lot of money.
Q. Can you detect contaminants at the bottom or near sidewall of the container?
A. Yes, ScanTrac's superior image processing technology detects defects reliably even near walls or bottom, something that is a challenge for other X-ray systems.
Q. Is the ScanTrac safe for the people around it?
A. Absolutely. Maximum stray radiation limits are strictly governed by the federal and state governments. However, we exceed their requirements by a wide margin. Furthermore, stray radiation from our equipment is usually below the natural radiation from the Earth and cosmic rays always present around us.
Q. Is X-ray inspection safe for our products?
A. The typical X-ray radiation dose received by the product during inspection is millions times less than the maximum allowable radiation dose established by the FDA.
Q. How fast can the ScanTrac inspect?
A. It can run up to 2,400 containers per minute at up to 700 feet per minute (210 m/min) conveyor speed.
