The applicability of plate thermometer (PT), which feature simple installation and low cost, was experimentally examined in steady and unsteady-state fire conditions. An infrared radiation heater and a square burner with C3H8 as fuel were used as heat sources. The relative measurement accuracy of the PT was evaluated by comparing measurements made using a Gardon-type heat flux meter. From a practical point of view and in terms of measurement accuracy, the optimal size and thickness of the PT in steady and unsteady-state fire conditions were 100 mm and 0.6 mm, respectively. These results can be explained by the conductive heat losses and thermal inertia of the PT for different sizes and thicknesses. It can be also concluded that measurements of heat flux using the PT in conditions of faster fire growth rate than slow require considerable attention.
