UNCERTAINTIES IN CALIBRATION OF AIR TEMPERATURE SENSORS

Jovan Bojkovski

Abstract

This paper describes sources of uncertainties in the calibration of air temperature sensors. Air temperature sensors are calibrated within different calibration environments. Depending on the environment, typical sources of uncertainties are analyzed and evaluated. In total, three different air temperature sensors, two platinum resistance thermometers in combination with resistance bridge and one digital thermometer are calibrated from -7 °C to 70 °C and from -40 °C up to 100 °C, in two different calibration environments. The reference temperature was determined using thermistors and calibrated platinum resistance thermometers.
