Abstract
Optical quotient thermometers are disposed on the operative end of pusher rods used to push coke from coke oven chambers. The actual value of the optical quotient temperature is measured by the thermometer on two closely-adjacent wavelengths and a quotient signal is produced from the top measured volumes which is converted in a measuring head secured to the pusher rod. An electrical signal is delivered by a converter in the measuring head by wires extending along the pusher rod to a point externally of the oven chamber to a recording and/or evaluating facility where the signal is recorded.
