[Verification Experiment] Master Chamber

Stability in the Master Chamber!? Verification Experiment

Stable even in winter!? Shortened cycle time!? Are you troubled by false judgments from differential pressure air leak testers? - Too many retries for no-leaking products... - Not fitting within the specified cycle time... - Test results are unstable in winter... The Master Chamber resolves these issues! 90% of users experience a 50% improvement in repeatability compared to without a master. [High performance] [Robustness] [Reliability] The MC series contributes to quality improvement. This time, we conducted verification experiments, so we hope you find it helpful.

basic information

1. 【Overview】 This study examines how the leak rate and the equivalent internal volume change and stabilize when a Master Chamber is attached compared to when it is not. The MC-2000B (Master Chamber) is continuously connected on the work side for verification. 2. 【Equipment Used in the Experiment】 - LS-R902 (Air Leak Tester) x 1 URL: https://www.ipros.jp/product/detail/2000700603?hub=39+LS-R902 - MC-2000B (Master Chamber) x 2 (for work side and master side) URL: https://www.ipros.jp/product/detail/2000697149 3. 【Test Conditions】 Test Pressure: 100 kPa Pressurization Time: 2 sec Equalization Time: 3 sec Stabilization Time: 2 sec Detection Time: 3 sec

Verification of Equivalent Volume K(Ve) Measurement With Master 1st time: 1042.1 mL 2nd time: 1042.5 mL 3rd time: 1042.0 mL With Master: Decided on 1042 mL Without Master 1st time: 1126.1 mL 2nd time: 1124.6 mL 3rd time: 1124.1 mL Without Master: Decided on 1124.1 mL **Results** The error increases significantly without the Master. The volume of the MC-2000B should be approximately 1000 mL. Since the tester volume (13 mL) and piping volume are included, the volume with the Master is more accurately measured. 2. Extracted Measurement Data Total of 35 times With Master Average: 0.0234 mL/min Standard Deviation: 0.0226 mL/min 3Σ: 0.068 mL/min Without Master Average: 1.090 mL/min Standard Deviation: 0.0310 mL/min 3Σ: 0.093 mL/min **Verification Results** Using the Master Chamber significantly reduced the average value and decreased the variation by 30%.

Cosmo’s Air Leak Testers began with the automation of cylinder block airtightness tests for engines in 1970. Our products are utilized in various fields including automotive parts, gas, water supply, medical, electrical, electronics, and food. In line with the overseas expansion of Japanese automakers, we began our own overseas expansion in 1983. We now have 24 sales and service offices in 13 countries. We are offering proposals and providing after-sales services overseas as in Japan. Currently, in order to support the electrification of automobiles, our products are being used for leak testing of parts for electrification such as battery cases and inverters as well as for fitting testing of electric power connectors. We are contributing to the efforts by our customers to prevent emissions of CO2. In various regions of South and Southeast Asia, we are donating pressure measuring equipment to technical schools to improve the quality of education and exchange technologies with local machinery manufacturers. We have been making every effort to help improve the industrial base through local manufacturing of high-quality leak testing equipment.
