使用補(bǔ)償導(dǎo)線的目的：

The purpose of using compensating wires is to:

a. 將熱電偶的參考端從高溫處移到環(huán)境溫度較穩(wěn)定的地方。

a. Move the reference end of the thermocouple from a high temperature location to a more stable ambient temperature.

b. 節(jié)省大量的用于制造熱電極的貴重和稀有金屬材料。

b. Save a significant amount of precious and rare metal materials used for manufacturing thermoelectric electrodes.

c. 使用補(bǔ)償導(dǎo)線便于安裝和線路的敷設(shè)。

c. The use of compensating wires facilitates installation and wiring.

d. 用較粗直徑和導(dǎo)電系數(shù)大的補(bǔ)償導(dǎo)線代替熱電極，可以減少熱電偶回路電阻，利于測(cè)量和自動(dòng)控制。

d. Replacing the thermoelectric electrode with a compensating wire with a thicker diameter and higher conductivity can reduce the resistance of the thermocouple circuit, facilitating measurement and automatic control.

使用補(bǔ)償導(dǎo)線時(shí)應(yīng)注意以下幾點(diǎn)：

When using compensating wires, the following points should be noted:

A. 各種補(bǔ)償導(dǎo)線只能與相應(yīng)型號(hào)的熱電偶配用，就是各種熱電偶和所配用的補(bǔ)償導(dǎo)線在規(guī)定溫度（0～100℃）范圍內(nèi)熱電特性須***是相同的。

A. Various compensation wires can only be used with corresponding models of thermocouples, which means that the thermoelectric characteristics of various thermocouples and the compensation wires used must be the same within the specified temperature range (0-100 ℃).

B. 補(bǔ)償導(dǎo)線和熱電偶連接點(diǎn)的溫度不得超過規(guī)定的使用溫度。

B. The temperature of the compensation wire and thermocouple connection point shall not exceed the specified operating temperature.

C. 補(bǔ)償導(dǎo)線和熱電偶、儀表連接時(shí)，正負(fù)極不能接錯(cuò)，而且兩對(duì)連接點(diǎn)要處于相同的溫度。

C. When connecting compensation wires, thermocouples, and instruments, the positive and negative poles must not be connected incorrectly, and the two pairs of connection points must be at the same temperature.

D. 要根據(jù)所配儀表的線路電阻要求，選用補(bǔ)償導(dǎo)線的線徑。

D. The diameter of the compensating wire should be selected according to the line resistance requirements of the equipped instrument.
