Abstract

Apparatus and associated methods relate to generating a temperature measurement signal based upon a weighted average of signals generated by a resistive temperature detector (RTD) (18) and a thermocouple device. The thermocouple device includes first and second thermocouple junctions (24A, 24B). The first thermocouple junction (24A) is thermally coupled to the RTD (18), and the second thermocouple junction (24B) is thermally isolated from the RTD (18). The thermocouple is configured to generate a signal indicative of a difference between first and second thermocouple junctions (24A, 24B), which is substantially equal to the difference between the RTD (18) and the second thermocouple junction (24B) due to the thermal coupling configuration. The RTD (18) generates a signal indicative of a temperature of the RTD (18). A weighted sum of the first and second signals is indicative of a temperature of the second thermocouple junction (24B), which responds rapidly to temperature fluctuations, due to its having a relatively small thermal mass compared with the RTD (18).
