6675 thermocouple pic
Vicky, actually i need the temperature to voltage conversion circuit part, the opamp stage, the linearization section. in some theory document i read linearization can be done either using extra circuit or using some polynomials in programming, but i can't get a clear picture of what i have to do.
as i have mentioned above i need to design temperature measurent system using thermocouple (it can be J,K,R, pt100(RTD) selectable ) and display the output temperature using microcontroller and lcd. which method of linearization should i adopt and how to proceed for that.
thanks a lot
