The report describes the use of common parallel thermocouple circuits for temperature control in thermal simulation. Iron-constantan thermocouples were welded directly to the basic metal being heated. Structural tests at elevated temperatures show that thermocouples connected into parallel electrical circuits and grounded to a common metal sheet give the same temperature measurements as separated thermocouples connected into a parallel circuit. This method is applicable to any test situation requiring average temperatures.
