LeakMatic Automatic In-line Leak Detector

The PBI-Dansensor LeakMatic gives 100% leak test of the packed product inline, in realtime. Tests package seal integrity. Using CO2 as a trace gas, so suitable for modified atmosphere package with minimum 10% CO2 in the pack. The LeakMatic leak detection system detects micro-leaks at ppm levels. Fast operation, able to test 5-7 cases of paked product per min. Ideal for fast M.A.P food package lines.

The LeakMatic is a non-destructive fully automatic in-line leak detector, using CO2 as trace gas. With the LeakMatic it is possible to leak test all your packages before they are leaving the packaging line. The LeakMatic detects micro leaks in flexible   and non-flexible packages containing a wide range of products like pasta, bread, cheese, meat, milk powder cans etc., directly from the packaging line.

The system has been designed to test several cartons or boxes containing numerous packages at once. The basic principle of the LeakMatic is that the package is placed inside a test chamber whereafter a user-defined vacuum is created. The vacuum will establish a pressure difference between the inside of the package and the test chamber causing CO2 from the package to enter the test chamber through even the smallest leak. A highly sensitive sensor measures all changes in the CO2 content and will detect even micro leaks.

Fast and sensitive
Using our highly sensitive CO2 sensor, the LeakMatic can test packages with a content as little as 10% CO2. The LeakMatic is designed to work in-line and can preform 4-5 full automatic leak detection tests per minute. This allows a 100% leak test of the entire production and minimize the risk of delivering leaking packages, which  in worst case can damage your company image.

Easy operation and self-diagnostic
On the front panel the LeakMatic has a graphical LCD touch screen from where the system can be set up and operated. The touch screen has back light and uses unmistakable icons to guide you through the various functions, furthermore the user interface comes in multiple languages versions, which makes the LeakMatic very easy to set up and to operate. The user interface has two user levels, the supervisor level can be password protected, allowing only authorised personnel to change the configuration of the LeakMatic.

The LeakMatic has a self-diagnostic function, which can be activated on the touch screen, the self test will also be launched automatically upon start-up, in case of an error, a message will appear in the display. Furthermore, no calibration of the sensor is needed as the sensor uses the CO2 content in the ambient air as background reference. The LeakMatic is furthermore built up in modules for easy service and maintenance.

The principle of operation
When the carton has been packed it is led by the conveyer belt directly from the packaging machine into the LeakMatic. When an optical sensor detects that a carton is in the test chamber, the vacuum chamber is lowered, creating a sealed chamber around the   carton. Now the automatic test cycle starts by evacuating the chamber to a user defined pressure, making the packages ballooning. In case of a leak some of the gas in the package will leak into the test chamber.

During the test, sample gas is continuously passing through the highly sensitive CO2 sensor. An increase in the CO2 level in the vacuum chamber indicates a leak in the packages. The leak is defined as the increase of CO2 in ppm/second.

Diagram of the LeakMatic

If no leak is detected the vacuum chamber is raised and the carton is automatically led out to a conveyor belt carrying it on in the process. As the chamber is raised a signal indicates that the LeakMatic is ready for the next test and as the tested carton is being led out a new is led in. In case of a leak, a signal indicates that the carton has to be removed from the packaging line. When being led out of the chamber, this signal can be integrated with various solutions for automatic removal of the leaking carton.

As the LeakMatic is controlled by a microprocessor it is not just a leak detector but also an advanced test unit with complete documentation of test results. The system features 16 set-up programmes with individual test parameters which can be defined and named/numbered for each package type.

All test results are added to the statistics in the programme used for that particular test. The set-up programmes can be password protected, whereby the users only can change between the existing programmes   and only users with password acces can alter programmes. The software is developed to have a very short start-up time and as well it provides a printer function and easy logging of all measurements.

The stored test results and test parameters can be transferred to a computer or to an external printer. The statistical data can also be shown in the display as: Total number of tests, number of items passing the test, number of items failing the test and number of items rejected by the operator.

The statistics are a very efficient tool for documentation of the product quality as no manual recording is needed. With the computer interface it is easy to export or print test statistics with time, date and programme or to transfer the data to a PC.

LeakStat Software

LeakStat Software
The new LeakStat software allows real time monitoring of the test from an external computer. Furthermore, the software stores all test data and easy facilitates comparison of tests data for various time periods or products.
