Abstract A multichannel temperature acquisition system performs a significant role in analyzing the performance of heat exchange equipment used widely in chemical process industry, refrigeration, and air conditioning, etc. Commercial stand-alone data loggers are available for temperature measurement but are not tethered to a computer to acquire real-time data. However, these data loggers are expensive and are mostly inflexible for adapting in academic research projects. To overcome these limitations, we describe in-house design, development, calibration, and implementation of a 12-channel temperature acquisition system using MAX6675 and Arduino Mega 2560 microcontroller. A low-cost Arduino Mega 2560 microcontroller is used here along with MAX6675 module which offers cold-junction compensation and digitization of temperature signal. Arduino Integrated Development Environment (IDE) is used as back-end software for programming and is integrated with MS Excel to store and display the acquired data. The acquisition system receives the data and processes it to further transmit to display or via an Ethernet driver to devices connected in local area network or connected through Wi-Fi. The developed system is calibrated with existing system and was found to have an accuracy of 99.8%. This system is implemented on heat exchanger device for enhancing convective heat transfer rate by incorporating the inserts inside heat exchanger tubes and determining temperatures at various locations.
