The electric insulation unit 4 is coupled to the detecting tube 2, and includes an insulator 41 covering the two wires 3 and preventing the two wires 3β from being short-circuited, and the insulator 4 [setting (4) pipe 2, The rim edge 7L 4 further includes a pedestal 42 ′ that is connected to the hollow portion 22 and is provided for the two-passenger portion 33. The insulation _ μ of the sub-cladding red-pulsing portion 33 is extended. The plug-in group 44 (not shown) of the 201000230 insulated cable 1. When the thermocouple of the present invention is used, 'the plug-in connection' is passed through the insulated electric power 43 and the base 42 to make the system and the detecting officer 2 Connected, and the detecting tube 2 has a change: when the 4th element is in contact with the hot liquid, the two wires (four)% of the gold to be tested will be first shovel, + wide* and hotter, and the thermoelectric effect L is first converted. The power difference is the difference, and the voltage difference is the analysis of the temperature difference between the sensing portion 32 of the wire 3 and the transmission portion 3. m 25 'heating is shown in Figure 4, as indicated by arrow 51 as the direction of the magnetic field" = two directions of the fluctuating magnetic field generated when the metal hydrothermal solution is rejected by the thrower; the current formed by the thermoelectric effect conversion passes through In the case of the sensing portion μ, an electromagnetic effect occurs due to the influence of the magnetic field direction 51, and since the two inductors 4 32 are alternately spirally wound, a plurality of small closed current loops are formed in a direction perpendicular to the direction of the magnetic field, and Generating an induced current 52 that flows in a counterclockwise direction as indicated by an arrow ,. When the induced current 52 of the adjacent two closed current loops meets at the intersection of the two sensing portions 32, the sensing is formed in different circuits. The direction of the current is in the opposite direction as indicated by arrow 53. Thus, the induced currents can cancel each other out, so that the induced current generated by the electromagnetic effect is prevented from interfering with the current generated by the thermoelectric effect, and the current is transmitted back to the early warning system. After calculation and analysis, a stable and correct temperature value can be obtained. With Figure 3, the design of many current loops can avoid the thermoelectric effect. The current continuously patrols in the single-current loop generated by the electromagnetic effect, resulting in partial current loss, thereby reducing the current flow analysis of the current transmitted by the early warning system 25 to the transmission portion 33 by the thermoelectric effect 9 201000230.

The thermocouple of the present invention having a twisted pair wire is measured after a period of use to obtain a stable and slightly smooth temperature profile, and the measured temperature is closer to the actual temperature and slightly higher than the conventional thermocouple. The obtained temperature is as described above, and the wire 3' which is spirally wound around the detecting tube 2 by the parent is formed in the sensing portion 32 by the electromagnetic effect to form a plurality of small closures. "k-way and the induced current in the same current direction in the mother-closed current loop, so that the induced current in the adjacent closed current loop can cancel each other at the intersection of the two conductors 3, thereby reducing the current generated by the thermoelectric effect. Interference enables the current to be transmitted back to the early warning system in a stable and accurate manner. It is worth mentioning that the position of the Hei HP 31 β of the thermocouple having the twisted pair 3 of the present invention has three kinds of positions: Referring to FIG. 6, the detecting portion 31 is abutting against the temperature measuring portion. 22 end faces. Referring to FIG. 7, the portion protrudes from the end surface of the temperature measuring portion 22, and both of the two aspects enable the detecting portion 31 to have a thermoelectric effect when heated, and the sensing portion 32 and the transmitting portion of the two wires 3 are 33 provides current. In summary, the thermocouple having the twisted pair wire of the present invention is spirally wound around the two wires 3 disposed in the detecting tube 2, and can be in the two wires 3 when the electromagnetic field is changed by the variable magnetic field 10 201000230. A plurality of small current loops are formed, each small loop affected by the electromagnetic effect generates an induced current flowing to the same $ direction, and the induced current is at the intersection of the induced current formed by the adjacent small loop at the two conductors 3 Because the direction of the induced currents is opposite to each other, the mutual interference of the current generated by the thermoelectric effect is reduced, so that the current can be stably and accurately returned to the early warning system 25', so that the present invention can be achieved.
