Hello!
I am trying to design a new way to accurately measure resistance on a automotive fuel level sender. I have a fuel level sender that uses a variable resistance strip that sends a resistance range between ~0 to 200 ohms to the fuel gauge. The float arm on the fuel sender moves the contact point from 0 to 90 degrees. 0 degrees maximum resistance at 200 ohms, 16 degrees at 150 ohms, 25 degrees at 100 ohms, 46 degrees at 50 ohms, 69 degrees at 25 ohms, and 90 degrees at 0-0.5 ohms. My design replaces the variable resistance strip with a potentiometer. Does such a potentiometer exist? thanks
