<p>A temperature probe (10) measures the temperature of a fluid which moves relative to the probe (10). The probe (10) includes a housing (14), a transducer (30), and one or more fins (28). The housing (14) has a bore (16) with a bore axis (18) and carries at least a portion of the fluid along the bore axis (18). The transducer (30) has a sensing length, and the fin (28) thermally couples to the transducer (30) along substantially the entire sensing length. The fin (28) is also substantially aligned with the bore axis (18) to promote laminar flow of the fluid in the bore (16). In a preferred embodiment the transducer (30) is held within a protective tube (32), and the fin (28) attaches to the tube (32) along a fin inner edge. The fin also attaches along a fin outer edge to a radiation shield (34) encircling the tube (32), the fin outer edge being shorter than the fin inner edge.</p> |
