Abstract

A temperature probe measures the temperature of a fluid which moves relative to the probe. The probe includes a housing, a transducer, and one or more fins. The housing has a bore with a bore axis and carries at least a portion of the fluid along the bore axis. The transducer has a sensing length, and the fin thermally couples to the transducer along substantially the entire sensing length. The fin is also substantially aligned with the bore axis to promote laminar flow of the fluid in the bore. In a preferred embodiment the transducer is held within a protective tube, and the fin attaches to the tube along a fin inner edge. The fin also attaches along a fin outer edge to a radiation shield encircling the tube, the fin outer edge being shorter than the fin inner edge.
