求4-20mA對應0-50.8mmHg. 請問6mA是多少mmHg. 12/16mA又是多少？另50.8mmHg=20mA 那50/25/15/5又是多少mA呢？請求算法。謝謝?

✔ 最佳答案
4-20mA之間有160-50.8mmHg之間有50.8
即是若按同等比例
每50.8/16 = 3.175mmHg/mA
6mA = (6-4)x3.175 = 6.35mmHg
12mA = (12-4)x3.175 = 25.4mmHg
16mA = (16-4)x3.175 = 38.1mmHg
50mmHg = 50/3.175+4 = 19.75mA
25mmHg = 25/3.175+4 = 11.87mA
15mmHg = 15/3.175+4 = 8.72mA
5mmHg = 5/3.175+4 = 5.57mA
