Emerson has introduced the Rosemount CT4215 Food and Beverage Leak Detection system. The Rosemount CT4215 is the first quantum cascade laser or tunable diode laser (QCL/TDL) continuous, inline detection system designed to help assure quality and safety, maximise production volume and decrease product waste for food and beverage products. The Rosemount CT4215 tests the seal and integrity of every bottle or package on a production line, detecting leaks at a sensitivity as low as 0.3 mm and automatically rejecting any defective bottle or package. This is in contrast to the traditional practice of testing occasional grab samples, which can leave a manufacturer vulnerable to unsafe food or beverages, reduced profitability and damaged reputation.

The Rosemount CT4215 installs directly on the food or beverage production line in a compact, selfcontained unit. The patented QCL laser technology measures CO2 and other gases used in food and beverage 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.

For the first time, food and beverage packagers can assure that every package leaving their facility is of the highest quality and can eliminate the returns and penalties associated with defects, while enabling any production issues to be identified and resolved within minutes.
