LEAK INDICATOR

摘要

The present invention concerns a liquid leakage detection apparatus. The apparatus includes a sample cavity, a housing with an opening and a housing contact face, an indicator body with an indicator body contact face, and a expansion element cavity between said housing contact face and said indicator body contact face. A liquid sensitive, expandable element is located in the expansion element cavity and a liquid path extends between the liquid collecting portion and the expansion element cavity.

主权项

1. A liquid leakage detection apparatus comprising:
a liquid inlet a sample cavity, a housing with an opening and a housing contact face, an indicator body with an indicator body contact face, and a liquid sensitive, expandable element, configured to expand between a contracted dry state and an expanded wet state; an expansion element cavity between said housing contact face and said indicator body contact face wherein the liquid sensitive, expandable element is located in said expansion element cavity; a liquid path between the sample cavity and the expansion element cavity; wherein the indicator body includes the sample cavity for collecting a liquid sample of the liquid collected by the liquid leakage detection apparatus; and whereby the liquid path extends through the expansion element cavity and past said expansion element cavity when said expansion element is in the contracted state.
