Brief Description: Capacitance Senders
|
|
Today, I had my friend Dwight show me how to solder electrical connections out at his hangar. I have decided to use capacitance fuel senders in my fuel tanks because they have no moving parts, they're more accurate than float senders throughout the range of values (if callibrated correctly) and they don't cost much. Each capacitance sender plate gets wired up inside the tank, so the connections need to be sturdy, protected from the fuel itself (i.e. special wire coating, proseal, etc) and protected from vibrations. I decided crimping and soldering would be best because once the tanks are closed up, I don't want to have to get in there again. After learning from Dwight, I went to Harbor Freight to get myself an inexpensive jeweler's setup. It is great for doing small electronic detail work. Then I soldered all the connections for the cap plates in all four tanks.
