МЕТОДИЧЕСКАЯ ПОГРЕШНОСТЬ ЭНЕРГЕТИЧЕСКИХ ПИРОМЕТРОВ, ОБУСЛОВЛЕННАЯ ВЛИЯНИЕМ НА РЕЗУЛЬТАТ ИЗМЕРЕНИЯ РАССТОЯНИЯ МЕЖДУ ПИРОМЕТРОМ И ОБЪЕКТОМ

Abstract

The reasons of energence of systematic methodical error in energy pyrometers caused by the influence object-pyrometer distance on measurement result are considered. It is shown that the reason of error is the non-synchronous alteration with distance of the solid angle under which from the object surface points the pyrometer input lens is visible and of the surface area the radiation of which falls on the pyrometer receiver. The recommendations decrease and on taking into account of this error are given.
