The detection sensor is mainly used for detecting the content of the enriched ferromagnetic particles. In the present embodiment, the detection sensor uses the force sensor 2. The force sensor 2 is fixed in the container bracket 3 through a backing plate and is positioned below the detection cavity 10, and the magnetic element 4 is fixed with the force sensor 2. The magnetic element 4 is influenced by the content of ferromagnetic particles, the pressure of which against the force sensor 2 changes, from which the content of ferromagnetic particles can be calculated.
