Abstract
An immersion sensor is configured to determine the content of a chemical element in molten metal. The immersion sensor has an auxiliary electrochemical cell extending from an interior surface into the internal volume of a sampling chamber. The sampling chamber can be integrally-formed in a sensor head or in a separate refractory structure. The immersion sensor may be configured for the flow of molten metal into the internal volume of the sampling chamber and into contact with the auxiliary electrochemical cell.
Claims24
An immersion sensor for determining the content of a chemical element in molten metal, the immersion sensor comprising:
- a sensor head located on the distal end of a carrier tube;
- a sampling chamber having an internal volume formed in a refractory structure;
- an inlet channel extending between the internal volume of the sampling chamber and a volume external to the immersion sensor;
- and
- an auxiliary electrochemical cell extending from an interior surface into the internal volume of the sampling chamber;
- wherein the immersion sensor is configured for the flow of molten metal from the external volume, through the inlet channel, into the internal volume of the sampling chamber, and into contact with the auxiliary electrochemical cell, wherein the inlet channel extends from a lateral interior surface of the sampling chamber to a lateral exterior surface of the refractory structure, and wherein the sampling chamber is disposed in an interior lumen of the carrier tube.
