PYROMETER

摘要

FIELD: measurement technology. SUBSTANCE: in given pyrometer there is solved problem of compensation of parasitic heating of tube of optical system thanks to making one or several holes through which informative radiation penetrates in blank plug of tube of optical system of reference conduit of pyrometer beyond boundaries of projection of reference receiving window. Similar holes can be also made in partitions of tube of reference optical system. EFFECT: raised measurement accuracy. 6 cl, 2 dwg
