Laser Heerkulbeeg: mabda'a of tallaabo. Laser heerkulbeegga fog (sawir)

cabbirka heerkulka laga yaabaa in xiriir iyo fog. Inta badan thermocouples, heerkulka iyo dareemayaal resistor oo u baahan xiriir la shayga, K. Cabirka heerkulkiisa ie.. Waxay waxaa si tartiib ah u samayn, laakiin waa qaali ahayn.

dareemayaal dhawaanshaha cabbiro shucaaca infrared ka shayga, siin natiijada degdeg ah, oo caadi ahaan loo isticmaalo si loo ogaado heerkulka dhaqaaqin iyo hay'adaha taagan in vacuo oodan iyo Reebnaan yaa sabab u ah colaad ah ee deegaanka, dabeecadaha qaab ama khatar ammaan. Qiimaha qalabka sida waa mid sare, inkasta oo mararka qaar u dhigma inaad la xiriirto qalabka.

thermometry monochrome

Habka Monochrome ee go'aaminta nuur guud isticmaalaa Milanello Fundka. Fulintii dhaxayn probes gacanta lagu fudud oo cabbirka fog fog si ay kombuyuutarrada gacanta casri ah jidaynayey si isku mar wada dhawrtaan oo shay iyo akhrinta heerkulkiisa in la galay xusuusta ama iyaga daabacaadda. dareemayaal taagan matalayo sida qalabka fudud oo heshiis korantada fog yar, iyo xoog sare leh aaladaha fog PID-control. optics Fiber, laser dooneysa, qaboojinta biyaha, joogitaanka ku soo bandhigay iyo scanner - optional socodka nidaamka doorasho iyo Hab kontaroolo.

Qaabeynta, shaandhaynta spectral, kala duwan oo heer kulka hawlgalka, optics, waqtiga jawaabta iyo iftiin ee shayga yihiin xubno muhiim ah oo saamayn waxqabad iyo waa in si taxadar leh loo arkaa in nidaamka soo xulidda.

shidma waxay noqon kartaa fudud oo laba-silig, iyo qalab-dareen sare Duugga u adkaysta adag.

Selection of jawaab spectral oo kala duwan heerkulka la xidhiidha hawlaha cabbirka gaar ah. wavelengths Short waxaa loo isticmaalaa heerkulka sare oo dheer ah - hooseeyo. Haddii shay yihiin hufan, tusaale ahaan, caaga iyo dhalooyinka, waa shaandhaynta uzkovolnovaya loo baahdo. band The nuugista filimka polyetylen CH waa 3.43 .mu.m. Go'doon of spectrum ee kala duwan this nayaa xisaabinta ee emissivity ah. Sidoo kale, qalabka galaas-sida noqdaan Doolaal ee Milanello ah 4.6 microns, kaas oo u ogolaanaya in si sax ah lagu ogaado heerkulka dusha galaaska. 1-4 microns saaro aagga u saamaxaaya in ay ka dhigi cabbirka via ee vacuum kormeerka furan iyo qolal cadaadis. Alternative - isticmaalka cable fiber-optic.

Optics iyo RTT waa qiimo lahayn in Xaaladaha intooda badan, tan iyo markii ay duurka ku of view of size of 3 cm fogaan ah 50 cm iyo wakhti jawaab ka yar 1 s filan. Waayo, go'aysa wax dhaqaaqaan yar ama si dhakhso ah lagama maarmaan noqoto in yar (dhexroor 3mm) ama ka yar cabirka (0.75 mm) kaalinta dheeraad ah. Far dooneysa (3-300 m) waxay u baahan yihiin sixitaanka indhaha, sidii beer isaga loo caadiga ah ee view uu noqonayaa mid aad u weyn. Xaaladaha qaarkood, habkan waxaa loo isticmaalaa radiometry laba ruxruxo. fiber indhaha u ogolaanaya in ay fogeyno korantada ka deegaanno dagaal badan, si loo baabi'iyo saamaynta buuqa iyo si ay u xaliyaan dhibaatada of helaan.

heerkulbeegga Laser asal ahaan gacanta ee kala duwan ee 0.2-5.0 waqti jawaab. jawaab Quick kordhin kartaa buuq signal iyo saamaynta gaabis ah ku dareen. Marka kululaynta induction u baahan yahay jawaab deg deg ah, iyo conveyor ah - ka gaabinaya jawaabta.

Monochrome IR heerkulbeegga waa mid fudud oo waxaa loo isticmaalaa in kiisaska alaabta oo tayo sare leh si ay u abuuraan gacanta heerkul ah waa mid aad u muhiim ah.

thermometry dual-Milanello

Waayo, hawlaha badan oo adag, halkaas oo saxnaanta cabbirka buuxda waa muhiim, iyo meesha alaabta la hoos geliyey wax stress jirka ama kiimikada, iyo khuseysaa radiometry laba-ruxruxo. Fikradda soo baxday in hore 1950, iyo isbedel dhowaan ka design ka mid ah hardware iyo kordhiyaan wax soo saarka iyo in la yareeyo kharashka.

Habka wuxuu ka kooban yahay in lagu qiyaaso mugga spectral xoogga laba wavelengths kala duwan. Heerkulka of shayga si toos ah ka akhrisan kartaa ka qalab ah, haddii emissivity oo isla for Milanello kasta. Tilmaamayaasha noqon doontaa run xitaa haddii duurka ku of view qayb xidhmey qalabka yara qabow, sida boodh, screens silig ee suuqa kala cawl iyo translucent. Habka Fikradda waa mid fudud. Haddii Milanello nuur labadaba waa isku mid (jirka ah cirro), Wehliyaha warshadu hawada waa la dhimay iyo xiriirka ka noqdo saami si heer kulka.

Dual-Milanello heerkulbeegga laser loo isticmaalo warshadaha iyo cilmi-baarista sida fudud, shidma gaar ah in yarayn kartaa baadi cabiraada.

Intaas waxaa sii dheer, heerkulbeegga multiwavelength dhigay qalabka oo aan jirkooda cirro, Wehliyaha nuugista oo kala duwan la Milanello. Xaaladahan waxaan u baahan yihiin falanqeyn faahfaahsan oo ka mid ah sifooyinka dusha wax ku saabsan xiriirka ka mid ah Wehliyaha ee Milanello, heerkulka iyo Halabuurka kiimikada ee dusha sare. Iyada oo data, kuwaas waxaa suurto gal ah in la abuuro isku geynta xisaabinta ku xiran shucaaca spectral at wavelengths kala duwan ee heerkulka.

xeerarka ku qiimaysay

Si loo qiimeeyo saxnaanta cabbirka user waa in ay ogaadaan waxyaabaha soo socda:

• dareemayaal IR muuqo ma kala midabo.
• Haddii dusha sare waa dhaldhalaalaan, markaas qalabka adkayn doonaa ma timaada oo keliya, laakiin sidoo kale tamar ka muuqataa.
• Haddii shayga waa hufan, waa shaandhaynta IR loo baahan yahay (tus, Doolaal galaas at 5 microns).
• In sagaal ka mid ah tobankii xaaladaha cabbirka gabi ahaanba sax ah ayaa loo baahan yahay. akhrinta soo noqnoqda iyo la'aanta eexda siin doonaa sax lagama maarmaanka ah. Marka isbedel siiyay nuur iyo processing waa ay adag tahay, waa in uu sii joogo laba ama radiometer multi-Milanello.
