  • Page 162  Figure 88 Magnetic Separation Principle Our SIPD family of products is also sensitive to helium and is based on a patented technology called Selective Ion Pump Detection (see the following figure). The sensor technology incorporates an ion pump connected to a quartz capillary tube and maintained under high vacuum.

  • Page 163: Methods Of Leak Testing

    Figure 89 Selective Ion Pump Detector Methods of Leak Testing There are many different ways to leak test parts using helium as a tracer gas. In general, the leak detection method is selected based on the actual working conditions of the part being tested. It is recommended that during leak testing, the same pressure differential be maintained and in the same direction as exists during the actual use of the part.

  • Page 164: Vacuum Testing Method (Outside-In)

    Locating Leaks To pinpoint the location of the leak(s) (but not measure the total leakage rate), helium is administered to the suspected leak sites of the part using a spray probe with an adjustable flow (see the following figure). Figure 90 Locating Leaks: Outside In...

    The part is placed in a volume that is then evacuated by the leak detector. All the helium escaping from the part is captured and quantified (see the following figure).
  • Page 166 A certain amount of time is given to allow leaking helium to accumulate in the shrouded area, increasing the helium concentration. The leak detector is then valved-in to the shrouded volume.

  • Page 167: System Leak Test Methods

    Helium is supplied to potential leak site using a spray probe or bagging suspected areas. If a leak exists, helium enters the system and rapidly diffuses through it.

  • Page 168: Typical Leak Detection Applications

    If a diluted helium mixture is used, the helium signal is diminished proportionally. For example, if a mixture of 10% helium and 90% nitrogen is used, the signal reads 10% of the actual value of the leak, or a decade lower.
