摘要： A multi-element thermocouple circuit includes at least two temperature measuring junctions. A first temperature measuring junction is formed by first and second thermoelements, each of the first and second thermoelements being formed of a noble metal or a noble metal alloy. The second temperature measuring junction, which connects to the distal end of the first thermoelement, is formed by third and fourth thermoelements, neither of which is formed from a noble metal or a noble alloy. A fifth thermoelement connects to the distal end of the second thermoelement and is formed of the same material as the fourth thermoelement. During operation, the distal ends of the third and fourth thermoelements define therebetween a first voltage difference corresponding to a temperature at the second temperature measuring junction, while the distal ends of the fourth and fifth thermoelements define a second voltage difference from which a temperature at the first temperature measuring junction may be obtained.

摘要： 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.
