Leak detection system ensures seal integrity

29 October 2018

Emerson has introduced the Rosemount CT4215 Food and Beverage Leak Detection System which uses laser technology to detect leaks, reject defective packages with no production slowdown. The Rosemount CT4215 is able to test the seal and integrity of every bottle or package on a production line, detecting leaks at a sensitivity as low as 0.3mm and automatically rejecting any defective bottle or package.

The compact, self-contained unit can be installed directly onto a production. A variety of customisable sampling heads are available for any package type including trays, pouches, bags, bottles and boxes.

The patented QCL laser technology measures CO2 and other gases used in packaging. A high-flow vacuum pump draws air from around the package or bottle and delivers this air to the measurement cell. If gas from a leaking product passes through the measurement cell, it will absorb some of the laser light. Less laser light reaching the detector means there is a leak. Any leak detected will trigger rejection of the package or bottle. The system requires few consumables, is low-cost to operate, and needs only regularly scheduled maintenance. It is easily installed on both new and existing production lines.
