2.1TheoryofOperationfor2‐ColorSensors

Two‐color ratio technologymakes possibleaccurate and repeatable temperaturemeasurements that

are free from dependence on absolute radiated energy values. In use, a 2‐color sensor determines

temperaturefromthe ratio ofthe radiated energies in twoseparate wavelength bands (colors).The

benefits of 2‐color sensors are that accurate

 measurements can be made under the following

conditions:

• Whenthefieldofviewtothetargetispartiallyblockedorobscured.

• Whenthetargetissmallerthanthesensor’sfieldofview.

• Whentargetemissivitiesareloworchangingbythesamefactorinbothwavelengthbands.

Anotherbenefitisthat2‐colorsensorsmeasureclosertothehighesttemperaturewithinthemeasured

spot(spatialpeakpicking)insteadofanaveragetemperature.A2‐colorsensorcanbemountedfarther

away,evenifthetargetdoesnotfilltheresultingspotsize.Theconvenienceisthatyouare

notforced

to install the sensor at some specific distance based upon target size and the sensor’s optical

resolution.

2.1.1PartiallyObscuredTargets

The radiated energy from a target is, in most cases, equally reduced when objects or atmospheric

materials block some portion of the opticalfieldof view. It followsthat the ratio of the energies is

unaffected,andthusthemeasuredtemperaturesremainaccurate.A2‐colorsensorisbetterthana

1‐

colorsensorinthefollowingconditions:

• Sightingpathsarepartiallyblocked(eitherintermittentlyorpermanently).

• Dirt,smoke,orsteamisintheatmospherebetweenthesensorandtarget.

• Measurements are made through items or areas that reduce emitted energy, such as grills,

screens,smallopenings,orchannels.

•

Measurements are made through a viewing window that has unpredictable and changing

infraredtransmissionduetoaccumulatingdirtand/ormoistureonthewindowsurface.

2.1.2TargetsSmallerThanFieldofView

Whenatargetisnotlargeenoughtofillthefieldofview,orifthetargetismovingwithinthefieldof

view,radiatedenergiesareequallyreduced,buttheratiooftheenergiesisunaffectedandmeasured

temperatures remain accurate. This remains true as long as the background temperature

 is much

lowerthanthetarget’s.Thefollowingexamplesshowwhere2‐colorsensorscanbeusedwhentargets

aresmallerthanthefieldofview:

• Measuring wire or rod — often too narrow for field of view or moving or vibrating

unpredictably.Itismucheasiertoobtainaccurate

resultsbecausesightingislesscriticalwith

two‐colorsensors.

• Measuring molten glass streams — often narrow and difficult to sight consistently with

single‐wavelengthsensors.

2.1.3LoworChangingEmissivities

Ifthe emissivities in both wavelengths (colors) werethe same, astheywouldbeforanyblackbody

(emissivity=1.0)orgraybody(emissivity<1.0butconstant),thentheirratiowouldbe1,andtarget

emissivitywouldnotbeaninfluence.However,innaturethereisnosuchthingasa

greybody.The

emissivityofallrealobjectschangeswithwavelengthandtemperature,atvaryingdegrees,depending

onthematerial.

When emissivity is uncertain or changing, a 2‐color sensor can be more accurate than a 1‐color

instrument as long as the emissivity changes by the same factor in both

wavelength bands. Note,

however,thataccuratemeasurementresultsaredependentontheapplicationandthetypeofmaterial

beingmeasured.To determine how touse 2‐color sensorswith your application when uncertain or
