CASSEL metal detector XPB for boards, felts and webs


The XD BOARD x-ray system is specially designed for detecting metal contamination in very thin but flat products. This makes it ideal for fabrics, non-woven fabrics, cardboard or even special cardboard such as transformer cardboard.

With the innovative XIA3 software system, parts of the product may be hidden. This proves effective for packaged products, where the actual packaging should not be examined for foreign bodies. Unnecessary false rejection of products can be prevented with the masking function.

CASSEL X-ray Features & Benefits

User-friendly operation: Cassel X-ray inspection systems have a large 17” color touch screen and intuitive software. Operations are simple and user-friendly. The production staff will not need any special training to work Cassel X-ray systems.

Real time detection with colored contamination analysis: The X-ray inspection systems detect foreign bodies with maximum sensitivity. In real time, contaminated products are detected and can be sorted out quickly and safely. On the large screen of the X-ray inspection device, foreign bodies are visibly highlighted with colored icons.

Masking functions: With the innovative XIA3 software system, parts of the product may be hidden. This proves effective for packaged products, where the actual packaging should not be examined for foreign bodies. Unnecessary false rejection of products can be prevented with the masking function.

24 hour non-stop operation: Thanks to the unique design and high quality components, Cassel systems can operate continuously for 24 hours a day, 7 days a week.

Reliable German safety standardsTÜV-approved: With their ingenious designs, Cassel X-ray inspection systems offer maximum safety and comfort for daily operations. In compliance with all security devices the radiation leakage level is extremely low: only max. 3 µSv / h or less. Every unit is extensively tested before delivery.

Ethernet and USB: Standard Cassel X-ray devices are delivered with USB and Ethernet interfaces. You can connect our X-ray systems to your network.

Auto storing of inspection data, with time/date stamp: Cassel X-ray systems are equipped with an automatic memory function. This allows you to save all quality control data quickly and easily. The data of all tested products can be stored, or you can opt to only store data for contaminated products. All images are saved with a time and date stamp in order to simplify the analysis and verification of data.

The process control System “SHARKNET®” is optional and allows you to automatically save the collected operational data and comply with certification programs and HACCP requirements.

Built-in remote maintenance: To avoid expensive travel costs and ensure quick solutions, Cassel X-ray inspection systems can be set and maintained without the presence of on-site technicians, no matter where your X-ray machine is located.
