Experimental measurements are made with a novel two wire thermocouple. Signals from two wires of unequal diameters are recorded from the thermocouple suspended in constant flow with a periodic temperature fluctuation. It is demonstrated that the reconstructed signal from the two wire thermocouple requires no compensation for &ohgr;≤2&ohgr;1where &ohgr;1is the natural frequency of the smaller wire. A compensation factor is recommended for larger frequencies &ohgr;≳2&ohgr;1.
