前言镍铁—硅考铜热电偶系新型无需冷端补偿之航空热电偶。所谓无需冷端补偿,是指热电偶冷端不需接上补偿导线补偿冷端温度变化对热电偶电势的影响而言。其原因是该热电偶在0～100℃范围热电偶的热电势很小,几乎趋近于零,也就是说热电偶在使用时,冷端温度高达100℃左右时所产生的电势对热电偶电势影响完全可忽略不计,这就是该热电偶的一大特点,它和另一种航空热电偶镍钴—镍铝热电偶具有相同的特点,该种热电偶在0～300℃范围内
Preface Ferronickel-silicon copper thermocouples are new aeronautical thermocouples that do not require cold junction compensation. The so-called without cold junction compensation, refers to the thermocouple cold junction without the need to compensate for compensation wire compensation cold junction temperature changes on the thermocouple potential terms. The reason is that the thermocouple in the 0 ~ 100 ℃ range thermocouple thermoelectric potential is very small, almost close to zero, that is to say when the thermocouple, the cold junction temperature up to about 100 ℃ when the potential generated by the thermocouple The potential effect is negligible. This is a major feature of the thermocouple. It shares the same characteristics as another aeronautic nickel-cobalt-nickel-aluminum thermocouple of the aeronautical type, which is within the range of 0 to 300 ° C
