- Abstract
The objective of this work was to evaluate an aspirated psychrometer constructed under different thermocouple gauges. Were used three thermocouple copper-constantan gauge: 24 AWG (0.511 mm of diameter), 32 AWG (0.202 mm of diameter) and 40 AWG (0.080 mm of diameter). The thermocouples were placed into a single psychrometer and each one positioned side by side at a distance of approximately 30 mm each other. Hourly air temperature and humidity values obtained from each gauge were compared with the values obtained with a thermistor and capacitive hygrometer. The results showed that the thermocouple gauges used (24, 32 and 40 AWG) had high correlation and accuracy with values determined by the hygrometer (r² > 0.97, RMSE ≤ 3.91%).
