ABSTRACT
The article discusses the use of thermocouples in temperature measurements in boilers, ovens and petrochemical applications. It discusses the design and construction of a thermocouple, consisting of metal wires, and mentions the difficulties posed by small voltage signal of the thermocouples. It discusses the use of thermistors, Resistance temperature-detectors (RTDs) and Integrated Circuit (IC) sensors, to overcome design challenges associated with thermocouples.
