용 도: 미세한 누출부위 탐지를 위하여 cell 내부에 헬륨을 주입 후 핼륨누출검출기를 사용하여 누출부위 학인 사양: - MAXIMUM INLET PRESSURE / TEST : 15mBAR - AUTOMATIC CALIBRATION /\ - He PUMING SPEED / AT INLET PORT: 1.1L/sec - OPERATION : FULL AUTOMAYIC - DUAL Y2O3 FILAMENT 설 명: Leak detection is used to detect micro-openings, porosities, permeation through materials etc. The means of detection is a tracer gas: Helium. This gas is so light that it can penetrate microscopic cracks very fast. The analyzer cell measures helium partial pressure created by helium molecules that come from the leaking parts. These molecules are pumped in by the vacuum pumps of the helium leak detector and end up inside the analyzer cell. This partial helium pressure is converted into a flow rate. The analyzer cell is tuned to detect three gas species, hydrogen(H2), helium isotope and helium(He). |
