Abstract

Apparatus for detecting fluid leaks in hermetic parts in the manufacturing process, essentially characterized in that it comprises a differential pressure capturing device that includes two working chambers or enclosures, separated by a moving element in response to a pressure difference between said devices. Chambers, one of whose chambers is connected to a test fluid accumulator reservoir, chargeable to establish a pressure reference, and the other to a device for connection to the enclosure of the test piece; means for loading both chambers with identical test fluid pressures and for isolating them once loaded, and means responsive to displacement of the movable member to provide an indication of the leak or determining a selection maneuver for the verified parts.
