<p>A sensor (10, 110) for measuring a level (12, 112) of a fluid (14, 114) includes a member (16, 116) and a bobbin (20, 120) defining a cavity (22, 122) therethrough and configured for receiving the member (16, 116). The sensor (10, 110) also includes at least one inductive coil (18, 118) wound to the bobbin (20, 120), wherein the at least one inductive coil (18, 118) defines a plurality of symmetrical layers (30, 130) that each extend along an axial length (L) of the bobbin (20, 120). The sensor (10, 110) includes a float (38, 138) operably connected to the member (16, 116) and buoyant in a fluid (14, 114) having a level (12, 112) in a container (40, 140). The member (16, 116) axially translates within the cavity (22, 122) in response to a change in position of the float (38, 138) according to the level (12, 112) of the fluid (14, 114) so that an inductance of the at least one inductive coil (18, 118) varies in relation to a position (44, 144) of the member (16, 116) within the cavity (22, 122) and thereby in relation to the level (12, 112) of the fluid (14, 114).</p> |
