Dual sensor radiation pyrometer.

摘要

A pyrometer for determining the temperature of a surface in the presence of reflected radiation has two infrared radiations sensors, each responsive to different wave length, positioned to receive radiation from the surface. An adjustment factor is developed from sensor response signals when reflected radiation and surface temperatures are the same, and is combined with sensor response characteristics over a range of surface and sensor indicated temperatures to develop a correction factor which when multiplied by the indicated temperature provides the actual surface temperature.
