초록

Disclosed are apparatus and methods of remotely detecting leakage into an evacuated space to detect the location of the leak. A number of pressure gauges continually monitoring pressure, rise in pressure and the rate of that pressure rise of the space. The locations nearest a leak will detect the pressure rise earliest in time and will have the highest rate of pressure rise. The distance between any one location and the leak being directly proportional to the time required for the increase in pressure to be observed at the location and inversely proporti...

청구항

Apparatus comprising: an evacuated space defined at least partially by a boundary layer; a plurality of spaced-apart pressure gauges in communication with the evacuated space at known locations within the evacuated space; each pressure gauge has means for detecting pressure rise and rate of pressure rise within the evacuated space adjacent the pressure gauge, and means for generating a signal corresponding to the detection of pressure rise and rate of pressure rise; and means for receiving and processing the signals generated by the pressure gauges to id...
