Abstract
A simple and reliable anticipatory failure indicator is provided for fluid circulation piping, and a fluid cooling arrangement including such an indicator is provided. The indicator includes a first sacrificial member, which is designed to be in direct contact with the fluid within the piping and designed to be weaker than the piping. The indicator includes a chamber, which is isolated from the fluid circulation at least partly by means of the first sacrificial member. The indicator includes an electrical response member, which is arranged into the chamber and which is configured to produce an electrical response upon exposure to the fluid, which has entered to the chamber via a failed sacrificial member. Accordingly, the indicator is configured to provide an electrical response as a direct indication of a failed sacrificial member and as an anticipatory indication of failed piping.
