ROD THERMOMETER DEVICE FOR DETECTING A TEMPERATURE, USE FOR THE ELECTRICAL SIMULATION OF NUCLEAR FUEL RODS |
摘要 |
The invention relates to rod thermometer device for detecting a temperature, including a plurality of temperature-sensitive elements and a protective sheath having an axis X in which the sensitive elements are partially inserted. The sheath is made of a metal constituting one of the two metals of a thermocouple, and the sensitive elements of a plurality of wires made of a metal other than that of the sheath and constituting the other one of the two metals of a thermocouple, one of the ends of each one of the wires being welded inside the sheath forming a junction for measuring a given thermocouple, the welded ends of the wires being distributed along a plurality of axial and azimuth positions relative to the axis X inside the sheath, each one of the wires extending out of the sheath by at least one of the ends thereof. |

1. A device for detecting temperature, forming a rod thermometer, comprising:
a plurality of elements sensitive to temperature; and a protective cladding of longitudinal axis X in which the sensitive elements are partially housed, characterized in that the cladding is made of a metal constituting one of the two metals of a thermocouple, and in that the sensitive elements consist in a plurality of wires made of a metal different from that of the cladding and constituting the other of the two metals of a thermocouple, one of the ends of each of the wires being welded to the interior of the cladding so as to form a measurement junction of a given thermocouple, the welded ends of the wires being distributed in a plurality of axial and azimuthal positions relative to the axis X in the interior of the cladding, each of the wires exiting from the cladding via at least one of its ends. |
