Linearization Circuit with Simplified Thermocouple Interface for Hot or Cold only Measurement

Abstract

The simpler thermocouple interface with linearization circuit is shown in this paper. Because of their robustness and wide temperature range, temperature-sensing thermocouples are commonly utilised Temperature-to-emf junction with Seebeck effect, two dissimilar metals are employed. The widespread usage of microelectronics and computers has had a significant effect on sensor system design. Sensors are increasingly incorporating signal processing features, and digital-type sensors that are directly compatible with computer inputs are becoming more common. A unique linearization approach is used to the j type thermocouple in this paper for a more linearized output.
