在實(shí)際應(yīng)用中常把熱電偶的參比端稱為冷端。TXR-HF4補(bǔ)償導(dǎo)線特點(diǎn)分析
熱電偶冷端溫度補(bǔ)償?shù)姆椒ㄓ?．冰浴法常用在實(shí)驗(yàn)室，即把參比端溫度恒定在0度，但做起來成本高、難度大。
2．冷端溫度校正法常用在要求不高的現(xiàn)場，即當(dāng)冷端溫度無法恒定為0度，就需要對儀表的指示值進(jìn)行修正。做起來容易但誤差較大。
3．補(bǔ)償電橋法較少單獨(dú)使用，是利用不平衡電橋產(chǎn)生的電勢來補(bǔ)償熱電偶冷端溫度變化所引起的熱電勢變化值。補(bǔ)償電橋有單獨(dú)產(chǎn)品，也有做在儀表內(nèi)的。
4．補(bǔ)償導(dǎo)線法這是zui常用的方法，即把熱電偶延長把冷端引至溫度較穩(wěn)定的地方(通常為控制室)，然后由人工來調(diào)正冷端溫度，TXR-HF4補(bǔ)償導(dǎo)線特點(diǎn)分析，即把儀表零點(diǎn)調(diào)至室溫,或由儀表內(nèi)電路進(jìn)行自動補(bǔ)償。對于貴金屬熱電偶把熱電偶延長也是不可能的，因?yàn)閮r格太高行不通，就用熱電特性相近的賤金屬來做延長導(dǎo)線，中間溫度定則是應(yīng)用補(bǔ)償導(dǎo)線的理論基礎(chǔ)。補(bǔ)償導(dǎo)線并不能自動補(bǔ)償熱電偶冷端溫度的變化，僅只是將熱電偶冷端引至溫度較穩(wěn)定的地方而已，補(bǔ)償還要由人工和儀表來進(jìn)行。因此補(bǔ)償導(dǎo)線應(yīng)該叫做熱電偶延長線，這樣才不會給人造成錯誤的理解。
1.工作溫度：zui高200℃和260℃兩種。
2.zui低環(huán)境溫度；固定敷設(shè)-60℃；非固定敷設(shè)-20℃。
