Abstract
The disclosure relates to a device for detecting the presence of a chemical contaminant. The device comprising a resilient indicator element which is biased into a first position and is anchored in the first position by means of a failure element. The failure element is made of a material which fails in the presence of a chemical to be detected, thereby releasing the indicator element from its first position and allowing it to move under its own resilience into a second position in order to provide an indication of the presence of the contaminant.
Claims9
A device for detecting the presence of a chemical leakage, the device comprising an indicator element which is held in a first position by means of a failure element which is held in tension, the failure element fails in the presence of the chemical leakage, thereby releasing the indicator element from its first position and allowing it to move into a second position in order to provide an indication of the presence of the leakage, wherein the failure element comprises a number of different materials for detecting different chemical leakages arranged in series and/or in parallel.
