本文推荐的热电偶设计是这样一种设计，由于沿杆和导线的热传导，对观察到的emf的校正在附图中给出的限制内。参照附图，可以看出，对热电偶或杆的直径没有限制，并且纵向尺寸以线和杆直径表示。阀杆的类型，如填充陶瓷原料、耐火绝缘管等。，也可供选择。因此，导线和支撑杆的尺寸可以在很宽的范围内变化，以匹配要限制或控制传导误差的特定要求。

The thermocouple design recommended herein is presented as one for which the correction to the observed emf, because of thermal conduction along the stem and wires, is within the limits presented in the accompanying figure. On referring to the figure, it is seen that no restriction is placed upon the diameter of the thermocouple or stem, and the longitudinal dimensions are expressed in terms of wire and stem diameters. The type of stem, such as packed ceramic stock, refractory insulating tubing, etc., also is left open to choice. Thus the sizes of wires and supporting stems may be varied over wide ranges to match particular requirements where conduction errors are to be limited or controlled.
