を備えた差動式熱感知器。In a differential heat sensor, in which the air in an air chamber equipped with a leak valve expands due to a sudden temperature rise and presses the diaphragm, closing the contacts and issuing an alarm, a shape memory alloy with a martensitic structure is used in the air chamber. A heating circuit is provided which is energized by a bellows attached to the alloy, and which energizes the alloy or the attached ζ wire, and this heating circuit is operated remotely to heat the alloy, thereby transforming it into the matrix structure. A differential heat sensor with a functional test device characterized by an inflated bellows.
