WebOur Dual Chamber Helium Bombing System features two ASME helium pressure chambers made of stainless steel, removable lids, and swing clamps for easy access when loading your test products.Bombing chambers are leak and pressure tested for full vacuum and operating pressures up to 100 PSI. System is controlled using our ATLAS Leak Test … WebThe bell jar method is widely applied for the helium leak test. In the bell jar method, helium gas is charged by depressurizing the work so that the concentration of helium gas is not decreased by atmospheric pressure. Gas in the chamber is sucked to detect leaked helium and judged by the detector.
Web13 jul. 2024 · 1.1 This practice covers procedures for testing and locating the sources of gas leaking at the rate of 1 × 10 −7 Pa m 3 /s (1 × 10 −8 Std cm 3 /s) 3 or greater. The test may be conducted on any device or component across which a pressure differential of helium or other suitable tracer gas may be created, and on which the effluent side of ... WebModern helium leak detectors can measure leakrates millions of times larger than in molecular flow. In conclusion, a helium leakdetector cannot measure air leakrates. Conversion from weight leak rate to volume leak rate In vacuum technology, the leak rate in general is described as volume leak rate (mbar.l/s).
