PT电阻阻值和温度关系表优质资料(可以直接使用，可编辑优质资料，欢迎下载）变化率为0.385Ω/℃,0℃时电阻值为100Ω,关系是线性的。如果现在温度是200度，那么PT100的电阻就是200×0.385+100=177Ω计算公式：PT100的电阻值=实际温度值×0.385+100ΩPT100在0摄氏度的时候电阻值为100欧姆，然后温度每升高一度，电阻值增加0.385欧姆，具有良好的线性。总的来说就是：变化率为0.385Ω/℃PT100电阻阻值和温度关系表下表列出了PT100铂电阻的温度和阻值对应关系温度0123456789（℃）电阻值（Ω）－3088.0487.6487.2486.8486.4486.0485.6385.2384.8384.43－2092.0491.6491.2490.8490.4490.0489.6489.2488.8488.44－1098.0395.6395.2394.8394.4394.0393.6393.2492.8492.44－0100.0099.6099.2198.8198.4198.0197.6297.2296.8296.420100.00100.40100.79101.19101.59101.98102.38102.78103.17103.5710103.96104.36104.75105.15105.54105.94106.33106.73107.12107.5220107.91108.31108.70109.10109.49109.88110.28110.67111.07111.4630111.85112.25112.64113.03113.43113.82114.21114.60115.00115.3940115.78116.17116.57116.96117.35117.74118.13118.52118.91119.3150119.70120.09120.48120.87121.26121.65122.04122.43122.82123.2160123.60123.99124.38124.77125.16125.55125.94126.33126.72127.1070127.49127.88128.27128.66129.05129.44129.82130.21130.60130.9980131.37131.76132.15132.54132.92133.31133.70134.08134.47134.8890135.24135.63136.02136.40136.79137.17137.56137.94138.32138.72100139.10139.49139.87140.26140.64141.02141.41141.79142.18142.66110142.95143.33143.71144.10144.48144.86145.25145.63146.01146.40120146.78147.16147.55147.93148.31148.69149.07149.46149.84150.22130150.60150.98151.37151.75152.13152.51152.89153.27153.65154.03140154.41154.79155.17155.55155.93156.31156.69157.07157.45157.83150158.21158.59158.97159.35159.73160.11160.49160.86161.25161.62160162.00162.38152.76133.13163.51163.89164.27164.64165.0165.40170165.78166.16166.53136.91167.28167.65168.03168.41168.7169.10180169.54169.91170.29170.57171.04171.42171.79172.17172.5172.92190173.29173.67174.04174.41174.79175.16175.54175.91176.2176.66200177.03177.40177.78178.15178.52178.90179.27179.64180.0180.39210180.76181.13181.51131.88182.25182.62182.99183.36183.7184.11220184.48184.85185.22135.59185.96186.33185.70187.07187.4187.81230188.18188.55188.92139.29189.66190.03190.40190
