A differential device for rapid temperature increases, characterized in that the sensor system is composed of two spirals of bimetallic sheet independent and juxtaposed, preferably superimposed, so that one of them can make contact with the other, or with means arranged in the other, so as to close an electric warning circuit when a rapid temperature increase occurs, obtaining the capacity of this system to perceive rapid temperature increases due to the fact that one of the spirals is exposed to the direct action of the environment to be perceived, while the other is more or less protected against the direct action of said environment, whereby, when a slow increase of temperature occurs, the two spirals move in unison, without the electrical contact between them being able to close, and instead, when a rapid increase in temperature occurs, the spiral exposed to the direct action of the environment is deformed with faster than the other, more or less protected, thus achieving an angular displacement between the contacts of both that will cause the contact in time calculated according to the physical characteristics given prior to the spirals.
