《谈谈动圈测温仪表的温度补偿》一文在《计量技术》一九七八年第三期刊出后,读者来信希望能给出R501型热敏电阻在各种不同温度时的阻值数据,并说明一下该电阻以用何种电桥测量为好。现谈谈这两个问题作为对前文的补充。 R501对应于每一温度应有一确定的阻值,变化不能超过某一较小的范围,否则对于因动圈电阻 “Talking about the dynamic temperature measuring instrument temperature compensation,” a article in the “Measurement Technology” published in 1978 after the third issue, the letter from the readers hope to give R501-type thermistor in a variety of temperature resistance data , And explain what kind of bridge to measure the resistance as well. Now talk about these two issues as a supplement to the previous. R501 corresponding to each temperature should have a certain resistance, the change can not exceed a smaller range, or because of dynamic resistance
