Abstract
This work has as an objective to evaluate in a experimental form, the calibration of temperature sensors, specifically, thermocouple K type, using a methodology as we can follow from the norm NBR 14610(Temperature indicator with sensor - Calibration by comparison with standard instrument) to do so we operated a linear regression in the commonly measured temperature range, in the Laboratory of Internal Combustion Engines of Universidade Federal do Para, with an estimated from the local temperature( ambient temperature 28°C) until 600° reached inside the combustion gases. For that purpose, it was build a bench of instruments with a series of integrated equipment in one whole system. The set is assembled by an electric oven with controlled temperature scale, data acquisition, and precision thermocouple, a computer unit equipped with software that supports the monitoring, recording, analysis and manipulation of the signals received by the data acquisitor. The results showed that the applied method is effective presenting acceptable errors within the ranges of uncertainties.
