Patent ID: 8689650

Claim:
An immersible probe assembly for molten metals comprising: a gas permeable baked sand-resin body having an immersion end and an opposed connection end adapted for being supported by a support lance and containing a communication connector providing electrical communication between said probe and remotely located monitoring apparatus; at least one molten metal testing device supported in the immersion end of said body, said sand-resin body allowing unobstructed gas flow through said immersion end, through said body and through said connection end, whereby gases released from a molten metal during immersion of said immersion end can enter and escape from within said probe through said connection end, a tube supporting the connection end, the end of said tube engaging a diametrically enlarged part of said sand-resin body which serves as a stop that limits the position of said tube relative to said immersion end, and a metal sampling mold embedded in said sand-resin body, a main body of said sampling mold being at least in part located in a part of said sand-resin body that protrudes toward the immersion end beyond said stop, an interface between said connection and immersion ends of the gas permeable baked sand-resin body forming a fault line for fracture of said gas permeable baked sand-resin body, such that a metal sample is released from said metal sampling mold when said metal sampling mold is struck by a hard structure, wherein said metal sampling mold is removed after retrieval of the metal sample.
