Subject field(s)

  • Atmospheric Physics
  • Thermodynamics
DEF

An instrument that determines the blackbody temperature of a substance by measuring its thermal radiation.

CONT

For many years radiation thermometers have been used to make non-contact temperature measurements of hot objects, particularly in industrial situations such as reformer furnaces, steel reheat furnaces, and ceramics kilns. ... Radiation thermometers work by detecting the radiant energy, typically over a restricted range of wavelengths, emitted by the object of interest and using Planck's radiation law to relate this energy to temperature.

CONT

A radiation thermometer is unable to distinguish between the radiation emitted by an object (the component that is related to the objects temperature) and radiation reflected by the object that originates from neighbouring objects.

OBS

Unlike other forms of thermometry, radiation thermometry is a non-contact technique and can be used to measure the temperature of remote or moving targets.
