METHOD AND DEVICE DETERMINING TEMPERATURE OF INTERNAL WALLS OF MULTIWALL VESSELS Russian patent published in 1999 - IPC

FIELD: measurement technology. SUBSTANCE: method determining temperature of internal walls of multiwall vessels is intended for use in high-temperature aggregates, for instance, furnaces in metallurgy, or for chemical technologies if vessel has at least one internal and one external walls and gaseous atmosphere, for example, air between them. Temperature of internal wall and if necessary temperature of gaseous atmosphere are determined by measurement of value characterizing temperature of external wall and by measurement of radiation of internal wall on three radiation frequencies as minimum. EFFECT: enhanced accuracy of temperature measurements. 15 cl, 3 dwg
