The type k thermocouple has a sensitivity of about 41 uv /°c, i. e. for each degree difference in the junction temperature, the output changes by 41 microvolts • if you have a 16-bit adc, what is the smallest temperature change you can detect if the adc range is 10 v?

ΔTmin = 3.72 °C

Explanation:

With a 16-bit ADC, you get a resolution of steps. This means that the ADC will divide the maximum 10V input into 65536 steps:

ΔVmin = 10V / 65536 = 152.59μV

Using the thermocouple sensitiviy we can calculate the smallest temperature change that 152.59μV represents on the ADC:
