Measurement uncertainty analysis of an electronic pressure scanning system
Abstract
An uncertainty analysis for multiple pressure measurements in windtunnel and turbine engine tests facilities is presented. The total system combines high-speed electronic multiplexing of transducer output with on-line calibration. The assumptions used in the calculations of the uncertainty and the effect of the on-line calibration procedure are discussed.
