Abstract:
Improved measurement of leakage in fuze seals is obtained by employing an r bubble leak indicator. The fuze to be tested is connected to an air supply line coming from an air bubble leak indicator. The air bubble leak indicator has a narrow orifice submerged in a liquid, which in turn is connected to an air supply. When the system has stabilized, any leakage from the fuze seals will result in air bubbles passing through the liquid. A light source and light detector placed at the outlet of the orifice will electronically detect bubbles and provide an electronic indication of leakage. The system also offers a visual indication of leakage. All parts of the unit being tested remain in a dry condition.
