|Researchers at Purdue University have developed an improved temperature measurement method that eliminates conduction errors within thermocouple probes. The conduction error arises from the temperature difference between the thermocouple junction, the measurement location, and the probe support. In current systems, conduction effects can account for up to 5 K of error. This is a major limitation within industries using gas turbines, where it is essential that temperature measurements be within tenths of a degree Kelvin to determine the propulsion system efficiency accurately. The newly developed technology consists of two-wire thermocouple probes with different thermocouple diameters. The two thermocouple readings combined with conjugate heat transfer simulations correct the temperature readings and deliver the actual temperature free of conduction error.
