Abstract This paper introduces the structures and working principles of platinum resistance air temperature sensor used in automatic weather station at present,and expounds its verification method.The uncertainty of measurement results is analyzed and evaluated by means of JJF1059.1-2012 Evaluation and Expression of Uncertainty Measurement.The origin and calculation method of class A and class B uncertainty of WUSH-TW100 platinum resistance air temperature sensor are analyzed in detail.And the synthetic standard uncertainty and the expansion uncertainty are calculated.
