NON-ORIENTED FLUID LEVEL SENSOR

摘要

A fluid level sensor (10, 40) comprising a body (19) including an axially extending post (16) configured for insertion into a container comprising a fluid and a float (18) having an opening (17). The post (16) may extend at least partially through the opening (17) in the float (18). A magnetic structure (22) may be coupled to the float (18) and a magnetic field sensor (21) may be coupled to the body (19) at a position axially spaced from and adjacent to an end of the float (18) for sensing magnetic flux imparted thereon by the magnetic structure (22) as the float (18) moves radially with respect to the post (16). Optionally, an annular magnetic shield (42) may be disposed at least partially within the post (16) and may define a cavity (44). The magnetic field sensor (21) may be at least partially disposed within the cavity (44). The annular magnetic shield (42) may optionally comprises an aperture (46) disposed proximate an end face of the annular magnetic shield 42 proximate the float (18).
