通过对动圈式温度仪表的改制,使这类仪表和热电偶在分度号不相符的情况下配套使用: 一、调整量程电阻R串为R串请看热电偶与动圈式温度仪表测量原理图。公式a=CI,其中C是表征仪表的固定灵敏度常数,指针的偏转角度α与输入的电流I成正比例关系。从图中分析:影响流过动圈电流大小的因素有热电势和回路总电阻。由于分度号不相符,热电偶产生的热电势值不可能相等。
Through the dynamic temperature instrument of the restructuring, so that such instruments and thermocouples in the case of sub-degree of inconsistency supporting the use of: First, adjust the range of resistance R string R series Please look at the thermocouple and moving coil temperature measurement instrument Schematic. The formula a = CI, where C is a fixed sensitivity constant characterizing the instrument, the deflection angle α of the pointer is directly proportional to the input current I. From the figure analysis: the factors that affect the size of the current flowing through the moving coil are the thermoelectric power and the total circuit resistance. Thermocouples can not generate the same thermoelectric potential due to the inconsistent indexing.
