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.
