LDS Systemtechnik ConturaZ TPIE 02 泄漏测试

The testing device can measure even the smallest leaks in packaging (helium detection)., The device is little used and in good condition., Information from the manufacturer’s brochure:, The detection limit of < 10-8 mbar l/s of the CONTURA Z can only be determined by mass spectrometric, Analysis can be achieved with a test gas., However, when sensitive flexible packaging is exposed to such a pressure difference,, the sealing seams could be subjected to such severe stress that the package could even burst., Such stress is eliminated by the patented membrane chamber principle of the CONTURA Z²., Function:, The product to be tested is placed manually or automatically on the bottom membrane. When the lid, is closed, the test procedure is initiated automatically., During the evacuation, the pressure of the atmosphere pushes the highly elastic membranes against the, packaging, and the contour of the product becomes clearly visible., The internal pressure of the packaging tightens the film from the inside, so that a balance of forces is established, (Internal pressure of the package = atmospheric pressure), which exerts no stress on the seals. The test is now carried out under vacuum without any deformation or inflation of the package. The escaping test gas is detected and quantified in the mass spectrometer., mass spectrometer (cf. ASTM 493, Method B)., Test result indicates the amount of leakage, but not the location of the leak., LEAK LOCATION, The critical points of the package can be examined with the standard sniffer probe. This allows the location of leaks in the package to be precisely determined., (cf. ASTM 499), HELIUM AS A TEST GAS, The noble gas helium (E989), which is used as a test gas, is ideal for leak tests., - Inert gas, therefore completely neutral and no harmful effect on the product, - Excellent detectability in the mass spectrometer, - Present in the atmosphere at only 5 ppm, - Easy to handle, - Unlimited approval as an additive to food, The low concentration in the atmosphere and the precisely definable concentration in the test object make helium superior to any other test gas., The detection limit is about 1,000 times lower than for CO2 and about 10,000 times lower than for N2., The test gas can be injected together with the shielding gas. The required helium concentration in the package is only about 3 to 6%., PRESENTATION OF TEST RESULTS, For easy and convenient operation, the Contura Z² is equipped with a multi-color 7 touchscreen., The test result is displayed as a leak rate value, a bar graph and a PASS/FAIL signal, which is indicated by a, green/red signal lamp. This ensures an objective test result independent of the operator. The Expert and Setup modes are additionally indicated by a yellow light of the, Signal lamp displayed., With the implemented standard touchscreen software, tasks in setup and expert mode can be easily performed., The measurement results can be stored in the system and retrieved via USB for further processing. This allows for the automatic creation of complete documentation of the test results., Dimensions / weight: 800 x 1,133 x 1,130 mm, 350 kg
