Abstract
One of the most widely used data acquisition devices for temperature analysis is the CONTEMP a202, which works in conjunction with DAQfactory software, interpreting thermocouple temperature data, with type k being the most used because of its wide measurement range and data accuracy. However, access to this equipment becomes impractical given the license costs of DAQfactory and the CONTEMP acquirer. As a result, was studied the possibility of cheapening the data acquisition process using Arduino® in a diesel generator set WHITE, to compare the data obtained by the two methods and to create a correction parameter that reduces the error between the data recorded by the two acquisitions. The thermocouple generates an electromotive force (emf), which when connected to the board of the Arduino®, makes it possible to read the temperature in a certain environment. With the thermocouple output voltage ranges defined, it was possible to obtain the temperature ranges, and with the aid of the Arduino® programming, an approximate temperature of the medium was determined. In order to improve the obtained data, it was necessary to adjust the curves between both methods.
