When packs are compressed the volume inside the pack is temporarily reduced creating
areas of increased pressure inside the package. When these areas of increased pressure
encounter a defect in the pack seal the MAP gas used can escape the package.
The sample bar at the entry/exit of the passive roller head is connected to an air motor in
the CT4215 which continually draws in air from the passive roller head. Any MAP gas
leaking from the package will be drawn into the sample bars and through the leak detector
triggering the counter and product reject systems.
2.9.2 Keg/barrel
The keg/barrel sample head consists of a simple support frame and sample bar that can be
mounted easily onto an existing conveyor line.
A. Support frame.
B. Sample bar.
The sample bar MUST be installed < 25 mm (1 inch) above the height of the keg/barrel
being tested allowing the product to pass freely underneath the bar.
If CO
2
is leaking from around the valve on the keg/barrel it will be drawn into the sample
bar and detected by the analyzer.
