DEVELOPMENT AND VALIDATION OF THERMOCOUPLE FOR THERMODYNAMICS EXPERIMENT

Abstract

Undergraduate students often struggle with Thermodynamics due to a lack of hands-on experience with the devices and sensors discussed in coursework. Traditional experimental setups—such as engine test benches and HVAC systems—are prohibitively expensive and maintenance-intensive, limiting student access and requiring large group work that can reduce individual engagement. To address this issue, we developed and implemented a costeffective thermocouple calibration apparatus for use in undergraduate Thermodynamics laboratories. The equipment utilizes affordable, readily available components, enabling the creation of multiple identical setups within a constrained budget. This allows students to work in smaller groups, increasing interaction and individual learning opportunities. The apparatus supports instruction in key Thermodynamics concepts, including temperature measurement, sensible and latent heat, and the Seebeck effect. Results from implementation show improved student comprehension and engagement. This approach offers a scalable, practical solution for enhancing Thermodynamics education, with potential applications across engineering curricula seeking to improve experiential learning within limited resources.
