#114701 - Weekend off topic and My homework |
...fuel gauges in vehicles usually work by having a float on an arm in the tank, with a potentiometer driven by the arm. The resistance changes the current flowing in an ammeter circuit.
In a standard, rectangular tank, the volume is a linear function of depth. In a DRUM like tank, on its side, the volume/depth function is co-sinusoidal. Since any fool can linearise it with an 8052, I was wondering about using LINEAR electronics, whats the simplest way of linearising the transfer function ? nominally. O Ohms = full 500 Ohms = empty.
