Multiple thermocouple system for high temperature reactors
摘要:
A multiple thermocouple system for rapidly monitoring wall temperatures of a metal vessel and identifying those thermocouples having voltages and temperature readings above a predetermined level. In the system, a number of first metal insulated conductor wires are metal bonded to the metal vessel to provide hot first junctions, and a second conductor utilizes the vessel metal wall as a portion of the conductor together with an additional metal insulated conductor wire connected to the metal wall. The conductors of each thermocouple pair are connected to the terminals of a rapid switching device and subsequently connected by the switching device to a voltage measuring means, which can be a digital readout type millivoltmeter. If desired, the voltage output of each thermocouple pair can be compared by a computer with the voltage output from a conventional dual conductor reference thermocouple attached to the vessel wall to determine temperature deviations. Also, the voltage readout for those thermocouples showing temperature deviations exceeding a predetermined amount can be conveniently displayed on a cathode ray tube screen.
