Calibration of Type S Pt/Pt–Rh Alloy Thermocouples and Uncertainty Estimation

Abstract

Thermocouples are the most widely used thermometric sensors for different applications due to wide temperature rangeand high temperature measuring capability. They are simple temperature sensors and can be made in very small sizes toconvert heat into electricity. Additionally, they are inexpensive and one of the highly durable thermometer types. Thepurpose of this article is to perform the calibration of thermocouples with the comparison method and to calculate theexpanded uncertainty by determining the uncertainty parameters affecting the measurement
