Figure 14.Static characteristic of a reversible potentiometric
sensor.
The obtained ideal characteristics can significantly differ from real ones due
to the presence of various kinds of errors:
1. The dead zone.
The output voltage varies discretely from coil to coil, i.e. this zone
arises when, at a small input value, Uout does not change.
The magnitude of the voltage jump is determined by the formula: DU = U / W,
where W is the number of turns.
The sensitivity threshold is determined by the diameter of the winding wire:
Dx = l / W.
