ABSTRACT:
A device for measuring the temperature of an external moving filament is disclosed. The device includes dual thermal sinks or reference bodies; each reference body has two heat flow sensors that are matched in sensitivity and are connected in series. By utilizing dual thermal reference bodies, which are maintained at different temperatures, the device yields the absolute temperature of the filament by measuring the temperatures of the referenced bodies and the heat flow rates between each of the reference bodies and the filament. The device automatically calculates the proportionality constant between the heat flow rates and the temperature differences between the filament and the reference bodies and thus calculates the filament temperature. Each heat flow sensor has a row of sensitive elements or active junction lines that is not parallel to the path of the filament. This orientation of the sensitive elements provides more accurate temperature measurements even when the path of the filament should constantly change.
