BRICK CORE TEMPERATURE TESTING
An approximate brick core charge level in the furnace can be measured by taking a millivolt reading on the core
temperature sensor. This sensor is located on the right side of the storage brick cavity in the limit bar louvre
area. (See drawing reference #68 in the Exploded View Parts Diagram.) The millivolt reading (DC) can be
compared to the Core Temperature Graph below to correlate the reading to an approximate brick core tempera
ture. This reading is useful in determining proper core charging of the furnace.
