A SYSTEM OF WAVE THERMOANEMOMETER WITH A THERMORESISTIVE SENSOR

The paper contains a description of the principles of operation, const ruction and metrological properties of the system of a wave thermoanem ometer with a thermoresistive sensor. The development of thermoanemome ter systems and the construction of sensors is discussed and the achie vements of various researches, including the author, are mentioned. Th ree constructional variants of the thermoresistive converter are prese nted, as well as the block diagram of the wave thermoanemometer measur ing system, its mathematical model, and the results of simulations and empirical experiments together with their metrological analysis. The conclusions at the end of the paper highlight the advantages of the de veloped system and present some of its possible application in measuri ng technology. (C) 1998 Elsevier Science S.A.
