Abstract
A furnace temperature detector includes a spike thermocouple attached to a heating chamber; an overheat thermocouple attached to the heating chamber; an inner thermocouple installed inside a reaction tube; a temperature controller connected to the spike thermocouple and the inner thermocouple; an overheat controller connected the overheat thermocouple; and a control switch for directing the output line of the overheat thermocouple. When the furnace overheats, the overheat thermocouple detects the overheating and generates and outputs an electric signal corresponding to the overheating to the overheat controller; the overheat controller generates and outputs an overheat control signal. When the furnace is operating normally, the overheat thermocouple detects a furnace temperature and generates and outputs an electric signal corresponding to the temperature to the control switch; the control switch directs the output line of the overheat thermocouple to the temperature controller; the temperature controller generates and outputs a temperature control signal.
