Abstract
To improve the air temperature observation accuracy, a low radiation error temperature sensor is proposed. A Computational Fluid Dynamics (CFD) method is implemented to obtain radiation errors under various environmental conditions. The low radiation error temperature sensor, a naturally ventilated radiation shield, a thermometer screen and an aspirated temperature measurement platform are characterized in the same environment to conduct the intercomparison. The aspirated platform served as an air temperature reference. The mean radiation errors of the naturally ventilated radiation shield and the thermometer screen are 0.57â°C and 0.32â°C, respectively. In contrast, the mean radiation error of the low radiation error temperature sensor is 0.05â°C. The low radiation error temperature sensor proposed in this research may be helpful to provide a relatively accurate air temperature measurement result.
