Abstract
This study assessed the measurement errors and improvement of the spatial resolution through miniaturization of the plate thermometer used to measure the heat flux in a fire environment. As a result, the heat loss to the side of plate thermometer was found to have a significant influence on the measurement error through analysis of the measurement values according to the thickness and density change to the insulation installed on the back side of the plate. Based on the existing 10 cm square shape, it was also confirmed that the 3 cm size plate thermometer could measure the heat flux with satisfactory accuracy through miniaturization. These results are expected to be useful for accurate measurements of the heat flux at local locations in a fire environment.
