Aperture Proximity Effects in High Heat Flux Sensors Calibration



A V. Murthy, Benjamin K. Tsai, Robert D. Saunders


In transfer calibration of heat flux sensors, a correction for the irradiance distribution across the sensing area may be required when the sensing areas of reference and test sensors are different. A method to calculate this correction using well known equations for the configuration factors is presented. Also, estimates of the correction for test conditions corresponding to the transfer calibration technique in use at the National Institute of Standards and Technology (NIST) are given.
