| Nov 21, 2017 at 20:54 | comment | added | resolver101 | Thanks for getting back to me so quick. I'm sure its something easy im missing. The pressure sensor reads 0 to 100 bar. 0mA to 20mA is 0v to 5v range which is %100 of the possible readings. 4-20 mA is 1v to 5v and is 80% or 4v. The first 1v (0 to 4mA) just tells us the sensors has power and is working ok and reading 0 bar. What I need to workout is 0 bar to 100 bar (4 mA to 20 mA). you can see a diagram on the post here: arduino.stackexchange.com/questions/45485/… | |
| Nov 21, 2017 at 17:22 | comment | added | Mikael Patel | Please add a circuit (wiring). Also explain how you reasoned about dividing by 4 instead of 5. Last which model are you using; the pressure range depends on the device. 4-20 mA is 0-100% of the pressure range. | |
