MATHEMATICAL MODEL AND MEASURING ALGORITHM OF CONTINUALLY DISTRIBUTED SEMICONDUCTOR SENSOR OF A TEMPERATURE PROFILE IN NON-ISOTHERMAL FLOWS

Abstract: This paper proposes a mathematical model and a measuring algorithm for a semiconductor one-dimensional distributed sensor designed to measure temperature fields in non- isothermal liquid and gas flows. A sensor device, its equivalent circuit and a circuit for connection to a measuring circuit are described. A step-by-step measurement algorithm is proposed, which includes the necessary electrical measuring operations and an algorithm for mathematical processing of the primary measurement information in order to determine the measured temperature field.
