张丝仪表测量机构尺寸的变形也是引起张丝仪表温度误差的原因之一。本文通过对张丝仪表力矩温度系数和张丝支撑部分尺寸变化的分析,得出仪表全补偿时应采取的措施。
One of the causes of the temperature error of the wire instrument is the distortion of the measuring mechanism size of the wire instrument. In this paper, through the analysis of the temperature coefficient of the filament wire and the dimension change of the wire support part, the measures should be taken when the meter is fully compensated.
