Magnetic fuel sensor module for SA341/SA342 Gazelle

The fuel sensor head had been modified to a modern design, replacing the potentiometer based float sensor with magnetic hall effect sensor. From being inherently more precise this design also features a hermetically sealed from fuel electric part of the sensor.

Rotation of the magnet driven by float is sensed by using hall effect IC and after processing the sensor provides a continuous 0-5V analogue and frequency outputs;

This overcomes the main problem of instability of old sensor and also give mach better reliability.
