FUEL CELLS bipolar plates inspection

modusAOI MCS42

The system comes with four 42 megapixel cameras and a high-performance control unit. LED lighting including LED control is also included in the delivery. The entire picture of the image analysis is orthogonally calibrated.


This system can meet the toughest requirements for the inspection of bipolar plates in various production stages.

The system has been adapted to the high requirements of the inspection of bipolar plates. The image acquisition time of approx. 2,5 seconds with a resolution of 24 um is outstanding.

Inspection with the high-resolution system cameras is carried out using the tried and tested modusAOI software. Our production process is certified under ISO 9000.
