The Reduction of Random Uncertainty in Differential Temperature Measurements Using Common Leg Thermocouples
S&T Accomplishment Report

OSTI ID:3014567
- Idaho National Laboratory
The uncertainty quantification of random error is considered for common leg thermocouples (i.e., where one thermoelement is shared along the length of the TC for all other TC junctions present). The uncertainty is presented for both a common leg and individual, separate leg thermocouples. For Type K thermocouples a reduction in uncertainty by up to 3x is capable when differential temperatures, ?T, are within 150°C, and diminishes to little to no improvement above 150°C.
