Linear inductive fluid level sensor

A fluid level sensor comprising:

• an inductive coil element including a bobbin having a cavity therein receptive of a core linked to a fluid in a container and a coil encircling the bobbin defining thereby at least one layer of the coil, the at least one layer extending over a first portion of the bobbin;
• wherein at least one other layer of the coil extends over a second portion of the bobbin less than the first portion of the bobbin;
• and
• a circuit connected to the inductive coil element including means for alternately charging and discharging the inductive coil element generating thereby a signal indicative of the level of the fluid in the container.

An inductive coil element comprising:

• a bobbin;
• and
• a coil encircling the bobbin defining thereby at least one layer of the coil, the at least one layer of the coil extending over a first portion of the bobbin;
• wherein at least one other layer of the coil overlaps the first layer and extends over a second portion of the bobbin less than the first portion of the bobbin;
• wherein the at least one layer of the coil and the at least one other layer of the coil include at least one boundary thereof in common.
