Abstract
Apparatus for monitoring the product temperature in an open ended furnace of the secondary emission type, the furnace having a plurality of serially arranged heating zones therein and including a conveyor which passes through the muffle of the furnace for carrying product thereon through the furnace. The furnace includes apparatus for adjusting the temperature in each of the zones. At least one cable passes through the furnace superimposed of the conveyor and carries thereon a plurality of temperature sensors which are serially arranged along the cable. The sensors are connected externally of the furnace to provide external monitoring of the temperatures in at least preselected zones (critical zones) of the furnace while the cable is provided with sag inhibiting apparatus to keep tension on the cable when the furnace is in operation.
