3. Use error propagation methods to derive the expression shown below for the uncertainty in 3. 2π 2 AT 2 ²³ (2²7)² (+)² + (0)² Δζ = = very Hint: Chain rule multiple times. Calculus is your friend. Follow the process and it is easy! Derive the partial derivative with respect to T, and then you can deduce the partial derivative with respect to C (i.e. you can just give the answer, don't repeat yourself).
A thermistor shows a large change in resistance for a small temperature change. Suppose one thermistor has a calibration curve given by R(T) = 0.5e-10/T where T is absolute temperature. What is the static sensitivity [Q/] at (i) 283K, (ii) 350K?
Annealing is a critical process in semiconductor manufacturing where silicon wafers get rapidly heated to get temperatures using powerful infrared heaters. Annealing helps to reduce defects in materials after implantation or deposition processes. a) You have been asked to design a temperature sensor an annealer with a range of up to 1500°C.Select a suitable thermocouple from the table below and give an explanation for your choice. 80 E 70 60 K 50 40 -C 30 20 10 0. 500 1000 1500 2000 2500 Temperature ("C) b) To record the temperature, you use a microcontroller with an ADC. The ADC is referenced to a 2.048V reference voltage source. To make use of the entire range of the ADC, what gain does the amplifier require for your chosen Thermocouple? c) You want to read the temperature with a resolution of 0.5°C.
