TEMPERATURE INDICATOR FOR USE IN A PRESSURIZED ENVIRONMENT

摘要

A temperature indicator for providing a visual indication that a pressurized fluid has exceeded a specified temperature. Such pressurized fluid being contained within a container bounded by a container wall. Such container wall being provided with an aperture for mounting of the temperature indicator therein such that the temperature indicator protrudes through such aperture and into such pressurized fluid contained within such container. The temperature indicator includes a housing member, a cavity provided in the housing member and a bore extending from an interior portion of the cavity to an exterior surface of the housing member. The exterior surface of the housing member is visible from a position external of such container when the temperature indicator is mounted in such aperture such that the temperature indicator protrudes through such aperture and into such pressurized fluid contained within such container. The temperature indicator further includes a plunger member at least partially disposed within the cavity. The plunger member extends into the bore and a bonding agent bonds the plunger member to the housing member. The bonding agent being substantially exposed to such pressurized fluid contained within such container and the bonding agent being thermosensitive to substantiallyrelease the bonding of the plunger member to the housing member upon the bonding agent substantially exceeding the specified temperature.
