Abstract
A burst temperature indicator system for determining when an electrical contact or other component reaches a predetermined temperature. In operation, a trace material may disperse into a surrounding environment, and be detected, when the electrical component reaches a predetermined threshold temperature. One or more foil barriers may be ruptured or broken by temperature-induced gas pressure. According to another aspect of this disclosure, a rupture disk may be burst at a predetermined temperature to generate, or enable emission of, a light signal. According to another aspect, a rupture disk device acts as, or is associated with, an engine to drive one or more electro-mechanical and/or acoustic devices to signal the occurrence of a predetermined temperature.
Claims5
A device for responding to a condition of an electrical component, the device comprising:
- a reservoir;
- a compressible material located within the reservoir;
- a driven device;
- and
- a rupture disc for transmitting energy from the compressible material to the driven device to generate a signal that the electrical component reached a threshold high temperature.
