Practically Validated Adaptive Calibration Technique for Thermocouple using Optimized ANN

Artificial Neural Network (ANN) based intelligent temperature measurement technique operating in varying environments is proposed in this paper. The technique that automatically calibrates linearizes and compensates for the nonlinear response characteristics and complex nonlinear dependency of the sensor characteristics on thermocouple material. To demonstrate the potential of the proposed soft calibration circuit, it is subjected to simulation and validated online by real life data. Results show that the proposed intelligent technique has fulfilled the objectives.
