Given below is the response of several types of temperature

Given below is the response of several types of temperature sensors. Which type of temperature sensor has (a) highest sensitivity at low temperatures, (b) best linearity, (c) applicable for high temperatures? What does Fourier analysis of signals mean? What information can one extract once the analysis has been performed? How is this information useful to engineers?

Solution

Best linearity is of RTD

Thermocouple is capable for higher temperatues

Thermistor has highest sensitivity at low temperatures
