Abstract
A BOF drop-in sensor assembly includes a handle, a weight, a sensor, and a cage to protect the sensor. The weight includes a high density material having a density of at least 1.2 times the density of steel. The cage comprises crossed rods which are easily melted and which allow molten steel to quickly envelop the sensor providing a highly reliable and accurate reading.
