Abstract:
1. A method of probing an electrically conductive target material in a metallurgical vessel, said method comprising the steps of: immersing a sensor in the target material; moving the sensor on a movement path in at least one direction in the target material, the movement path extending through at least one molten metal or semiconductor material; acquiring a measurement signal from the sensor while the sensor is moving on the movement path in the target material, the measurement signal being indicative of electrical conductivity in the vicinity of the sensor; and generating, based on the measurement signal, a signal profile indicative of the electrical conductivity as a function of the sensor movement, wherein the method further comprises the steps of operating at least one coil in the sensor to generate an electromagnetic field around the sensor, and generating the measurement signal to represent momentary changes in the electromagnetic field.
