<p>The present invention provides cost-effective thermal detection elements having a controlled relationship between a thermal radiating and thermal sensing element. The thermal detection element (10) comprises an insulating substrate (20) having a plurality of conductive interconnection elements (e.g., 25A, 26A, 27A, 28A) formed on the substrate to permit electrical connection of the substrate with other electrical components. A thermal radiating element (30) is at least partially embedded within the substrate and mounted such that it electrically communicates with at least one of the conductive interconnection elements. A thermal sensing element (40) is mounted adjacent the thermal radiating element such that a substantial portion of the thermal energy radiated by the thermal radiating element is channeled to the thermal sensing element. The thermal sensing element is also mounted such that it electrically communicates with at least one of the conductive interconnection elements. Through this configuration, low-cost, reliable, thermal detection elements are created which are surface-mountable and give accurate, reproducible signal outputs. <IMAGE></p> |
