Abstract:
A temperature sensing system comprises a conductive tube, a shape memory alloy (SMA) element, and a detector. The SMA element is disposed to create an electrical contact with the electrical tube when subjected to at least a critical temperature, and the detector is configured to identify an alarm condition when the conductive tube and the SMA element form a closed electrical circuit.
