Magnetic sensing device

A system comprising:

• a fluid container;
• and,
• a magnetic sensing device for sensing debris in a fluid of the fluid container, the magnetic sensing device comprising:
• a housing;
• a substantially cylindrical shield mechanically coupled to the housing;
• a magnet disposed within a cavity defined by the substantially cylindrical shield, wherein the magnet defines a countersunk cavity;
• and,
• a printed circuit board assembly (PCBA) disposed proximate to a first end of the magnet that is opposite a second end of the magnet, wherein the second end of the magnet is proximate to an end of the housing proximate to a medium being measured.
