Up to 24 images per particle station.
Up to 3 light techniques per particle
station.
Up to 4 particle stations.
Based on 3 particle stations:
up to 216 data points from particle
inspection per product.
Depending on product range and container type different 
illumination techniques
and combinations can be used.
------------------------
back
Each product is inspected in up to three particle inspection stations using the image subtraction method:
1 Container and liquid are rotated at high
speed by a servodrive in each position of
the inspection carousel.
2 Rotation of container is stopped, the liquid con-
tinues to move, particles move with the liquid.
3 A central inspection mirror moves synchro-
nized with the transport of the container.
4 The camera acquires a sequence of up to
24 images.
5 The images are sent to the image processor
and are compared to each other in an overlay
image, pixel by pixel.
Objects which change their location between the images are identified as particle defects. Using two or three particle inspection stations allow to vary the rotation speeds to detect lighter and heavier particles. The set points for rotation speed and brake point are stored together with the product inspection configuration (recipe) for each product. Programmable servo drives in every position of the inspection carousel allow reproducible rotation distances and rotation speeds. No belt drives - no abrasion.
