摘要： A fire heat sensor comprising a high-temperature detecting portion provided with a temperature detecting element which exhibits a fast heat response to a rise in ambient temperature, and a low-temperature detecting portion provided with a temperature detecting element which exhibits a slow heat response to a rise in ambient temperature. The fire heat sensor further comprises a resin member by which the high-temperature detecting portion and the low-temperature detecting portion are integrally formed so that heat energy is transferred from the temperature detecting element of the high-temperature detecting portion to the temperature detecting element of the low-temperature detecting portion. In the fire heat sensor, differential heat sensing is performed based on temperatures detected by the low-temperature detecting portion and the high-temperature detecting portion.

摘要： A fire sensor comprising a baseplate, a temperature detecting element, and a protective case. The baseplate has an outside surface which serves as a heat sensing surface which is exposed to a hot airflow generated by a fire. The temperature detecting element thermally contacts with the inside surface of the baseplate to detect the temperature of the baseplate. The protective case contacts with the radially outer portion of the inside surface of the baseplate to form a hermetically sealed space between itself and the baseplate. The temperature detecting element is confined within the hermetically sealed space. The baseplate has the temperature detecting element in approximately the central portion of the inside surface thereof and also has a shape and a material which meet the condition that the product of the thickness and heat conductivity of the baseplate is 1.1×10−4 (W/K) or less.
