Fuel Gauge: Description and Operation
Fuel Gauge
Description
The magnetic gauge movement consists of three primary coils, one of which is wound at a 90-degree angle to the other two. The coils form a magnetic
field that varies in direction according to the variable resistance of the sender unit that is connected between two of them. A primary magnet, to which
a shaft and pointer are attached, rotates to align to this primary field, resulting in pointer position. The bobbin/coil assembly is pressed into a metal
housing that has two holes for dial mounting. There is no adjustment, calibration or maintenance required for this gauge.
