检测机构实验室使用的测温补偿导线实际上是一对在规定范围内(0-100℃)使用的热电偶丝。它的热电性能与热电偶的热电性能相似,通常用于热电偶与一次仪表的连接。使用补偿导线时,应注意以下几个问题: 1、不能超出其规定温度范围使用。一般情况下,只有在0-100℃之间,补偿导线才有与热电偶一致的热电特性。如果与热电偶连接端高于100℃或二次仪表
The temperature compensation wire used by the testing laboratory is actually a pair of thermocouple wire used within the specified range (0-100 ℃). Its thermoelectric properties and thermocouple thermoelectric properties similar to the thermocouple usually used for a meter connection. The use of compensation wire, should pay attention to the following questions: 1, can not exceed the specified temperature range. Under normal circumstances, only between 0-100 ℃, the compensation wire has the same thermocouple thermoelectric properties. If the connection with the thermocouple above 100 ℃ or secondary instrument
