Fast response temperature sensor

Abstract From the Canadian patent

A fast response fluid temperature sensor is disclosed which consists of a silicon temperature sensing semiconductor chip mounted on an extremely thin fin having a high surface area to mass ratio. The fin and chip combination are mounted in a frame assembly, with the thermal conductivity of the frame assembly being high and the specific heat being low for maximum heat transfer from the fluid being sensed to the silicon chip. The chip and fin assembly are illustrated as being open to the free flow of fluid around the assembly no insulating material, is provided between the fluid media being sensed and the fin and chip assembly, and a protective cage is formed around the fin and chip assembly. …
