在某些现代工业生产过程中,对温度测量和调节有很高的要求。一般市场供应的仪表往往不能满足测量灵敏度与精确度的要求,为此就必须将仪表改制成窄量程的,测量范围只有二、三十度甚至几度,对这种仪表的改装和桥路参数的选择,我们作了一系列的试验,证明了改制是可能的,其关键在于仪表的温度附加误差。 In some modern industrial processes, there is a high demand for temperature measurement and regulation. The general market supply of instruments often can not meet the measurement sensitivity and accuracy requirements, for which it must be transformed into a narrow range meter, measuring only two or thirty degrees or even several degrees, the modification of this instrument and the bridge parameters We made a series of experiments to prove that the restructuring is possible, the key lies in the instrument temperature error.
