1)A copper -constantan thermocouple is to be used to measure temperatures between 0 and 200°C. The e.m.f. at 0°C is 0 mV, at 100°C it is 4.277 mV and at 200°C it is 9.286 my. What will be the non-linearity error at 100°C as a percentage of the full range output if a linear relationship is assumed between e.m.f. and temperature over the full range?
2) A thermocouple element when taken from a liquid at 50°C and plunged into a liquid at 100° C at time r = 0 gave the following e.m.f. values. Determine the 95% response time.
