Information:
For the quality assurance of heating elements it is possible to diagnose a direct contact between the filament and the outer wall by electrical measurements. But electric measuring methods can not give any information about the distance between the filament and the outer wall. However, the position of the filament can clearly be seen on the x-ray image. Only by the use of digital x-ray cameras a fast and efficient x-ray inspection becomes realisable. |
