Di intensiti fɔ infrarɛd raytin dipen pan ɔl tu di tin in tɛmpracha ɛn in sɔfays kwaliti dɛn. Di tɛmpracha we ay, dat min se di raytin go strɔng. di kכntribyushכn dεm na di sכfayz — spεshal εmisiviti — de afekt bak di rεdyushכn intεnsiti. Polish mεtal gεt rili lכw emissiviti (bכt 0.05-0.1), we min se mכst infrarεd rεdyushכn de rεflek pas fכ kכmכt. Di tin dɛn we nɔto mɛtal lɛk ɔksayd, plastic, ɛn pent gɛt ay emissiviti (lɛk 0.7-0.95), we de mek dɛn fayn fɔ mɛzhɔ infrarɛd tɛmpracha.

We yu de pik wan tɛmal kamɛra, tri paramita dɛn de disayd. Get eni wan rong en di rizulyt dem kompromi.
Fɔs: infrarɛd rizɔlt. Rizolushɔn de disayd di tɛmal imej klia — ay rɛsɔlɔshɔn min rich ditel insay di tɛmal imej. Di kɔmɔn rɛsɔlɔshɔn dɛn na 160×120 (lɛk 20,000 piksɛl), 320×240 (lɛk 77,000 piksɛl), ɛn 640×480 (lɛk 310,000 piksɛl). 160×120 rεsכlushכn suits kwik skan εn jεnarכl inspekshכn; 320×240 na di balans choice fɔ mɔs industrial aplikeshɔn dɛn; 640×480 fit fayn fayn analisis, lɛk fɔ no di minit tɛmpracha difrɛns na ilɛktronik kɔmpɔnɛnt dɛn.
Sɛkɔn: NETD (Noys Ikwivalɛnt Tɛmpratura Difrɛns). NETD de riprizent di sכm tεmprachכ difrεns we tεmral kεmεra kin rεsכlv, we dεn mכsu insay mK (millikelvin). Lכw NETD min hכy sεnsitiviti to sכm tεmprachכ difrεns. Jɛnɛral wan, kamɛra dɛn we gɛt NETD dɔŋ 50mK kin mit bɔku pan di industrial nid dɛn; dכn 20mK na prεmiכm gred, we fayn fכ risεch εn prεsishכn tεst.
Tɔd: di tɛmpracha rɛnj. Difrɛn aplikeshɔn dɛn nid difrɛn rɛnj dɛn. Ilektrikal ikwipmɛnt inspekshɔn tipikli nid -20°C to +150°C; industrial furnace inspekshɔn nid fɔ 0°C to +1000°C ɔ pas dat; bildin ɔt lɔs inspekshɔn nid -20°C to +60°C. Di PK63 siriɔs hanheld tɛmal kamɛra sɔpɔt -55°C to +1580°C, we de kɔba mɔs aplikeshɔn frɔm bildin inspekshɔn to mɛtalɔji.
Di thermal imaging prodakt layn we FangService sɔpɔt inklud tri mɔdel dɛn we de kɔba di ful spɛktrum frɔm ɛntri-lɛvɛl to pɔshɔnal. Fɔ ɔndastand di difrɛns na di las tin we yu fɔ du fɔ pik.
Di PK61 na poket thermal kamera we dɛn mek fɔ kwik skrinin. I kɔr advantej na pɔtabiliti — smɔl fɔ fit insay pɔkit, layt fɔ kɛr ɔl di de. Opareshɔn simpul: pawa on, aim, rid — tri step kɔmplit. I fayn fɔ: rutin tɛmpracha inspekshɔn fɔ ilɛktrik kabinɛt, kwik asɛsmɛnt fɔ HVAC sistem, ɛn fɔs lokalizɛshɔn fɔ bildin lik. Di PK61 gɛt mɔdaret infrarɛd rizɔlt ɛn NETD arawnd 50mK, we de mit di jenɛral inspekshɔn nid dɛn.
Di PK62 na infrared tɛmɔmɔta (IR gɔn) we dɛn mek fɔ mɛzhɔ di pɔynt tɛmpracha. Nɔ lɛk tɛmal kamɛra, infrarɛd tɛmɔmɔta de mɛzhɔ tɛmpracha na wan say — aim, prɛs, ɛn tɛmpracha nɔmba de apia na di skrin. di PK62 in advantej dεm na hכy prεsishכn (tipikli ±1°C to ±2°C), fast rεspכns (tipikli כnda 1 sεkכnd), εn rili lכw kכst. I fayn fɔ: prɛsis singl-pɔynt tɛmpracha mɛzhɔmɛnt, lɛk motoka biɛrin tɛmpracha, paip sɔfays tɛmpracha, ɛn tɛmpracha kɔntrol we dɛn de prosɛs it.
Di PK63 na wan hanheld ay-rɛzolushɔn tɛmal kamɛra, di prɔfɛshɔnal-grɛd mɔdel na di prodak layn. I gɛt ay infrarɛd rizɔlt, lɔwa NETD, ɛn wan big tɛmpracha rɛnj. Di PK63 de sɔpɔt bak vidio rikodin ɛn rial-taym tɛmpracha analisis, we fit fɔ aplikeshɔn dɛn we nid ditayl tɛmpracha data ɛn tren analisis. I fayn fɔ: ikwipmɛnt fɔlt diagnosis, R&D tɛst, ɛn aplikeshɔn dɛn we nid pɔshɔnal inspekshɔn ripɔt.
Tɛmal imej teknɔlɔji gɛt bɔku tin dɛn fɔ yuz na industri, kɔnstrɔkshɔn, ɛn sikyɔriti. Na di 4 tin dɛn we kin apin we pipul dɛn kin si.
Fɔs: prɛdiktiv mentenɛns fɔ ilɛktrik ikwipmɛnt. Ilektrikal kɔnɛkshɔn pɔynt dɛn (lɛk sɔrkwit breka, kɔntakta, bɔsba jɔyn) de mek abnɔmal ɔt we kɔntakt rɛsistɛns de go ɔp — dis na fɔs signal fɔ se di ikwipmɛnt dɔn pwɛl. We yu skan ilɛktrik kabinɛt dɛn wit tɛmal kamɛra ɔnda lod, yu kin no dɛn hot ples dɛn ya bifo tɛm, ɛn dis kin mek dɛn ebul fɔ mek dɛn mentenɛns bifo di ikwipmɛnt dɛn trip. Dis na di mɔs machɔ ɛn ay ROI aplikeshɔn fɔ tɛmal imej teknɔlɔji.
Sɛkɔn: bildin ɔt lɔs ditekshɔn. Difεkt dεm na di bildin εnvכlop insulεshכn de mek lokaliz tεmprachכ anomaly — insay winta, di εria dεm we nכ insulεt fayn de sho brayt (wam) insay tεmral imej dεm, we di εria dεm we insul fayn fayn wan de sho dak (kul). Tɛmral kamɛra dɛn kin fɛn di tin dɛn we nɔ fayn na di insuleshɔn kwik kwik wan, we kin gayd fɔ mek dɛn ripɛnt ɛn fɔ mek dɛn nɔ yuz bɔku ɛnaji fɔ mek dɛn ebul fɔ yuz dɛn bak.
Tɔd: industrial ikwipmɛnt kɔndishɔn monitarin. Abnɔmal frikshɔn na di ikwipmɛnt dɛn we de rɔta lɛk motoka, pɔmp, ɛn fan kin mek di tɛmpracha go ɔp. We yu de skan dɛn divays ya ɔltɛm wit tɛmal kamɛra, i de mek yu gɛt tɛmpracha bayslayn; wans dεn dεtekt abnכmal tεmprachכ rεs, dεn kin schedul inspekshכn.
Fɔs: fɔ wach di sikyɔriti. We layt nɔ de bɔku ɔ we dak ɔlsay, tɛmal kamɛra dɛn kin mek pikchɔ dɛn tru difrɛns we de bitwin di tɛmpracha, we dɛn kin yuz fɔ wach di sikyɔriti ɛn fɔ fɛn ɛn sev pipul dɛn.
Kɔmprɛhɛnsif tɛmal imej nɔto divays we yu de bay ɛn fɔgɛt — na wan kɔntinyu mentenɛns prɔses. Wan kɔmplit tɛmal imej wokflɔ fɔ inklud: fɔ mek di ikwipmɛnt tɛmpracha beslayn (fɔs inspekshɔn), fɔ ri-inspekshɔn wan wan tɛm (frikyuɛnsi bays pan di ikwipmɛnt krichɔ), abnɔmal tɛmpracha analisis (fɔ no if dɛn nid fɔ mentenɛns), post-mentenɛns verifyeshɔn (kɔnfɛm se di tɛmpracha dɔn kam bak to nɔmal), ɛn fɔ arkiv data (fɔ bil wan tɛm-siris tɛmpracha rɛkɔd).
We yu de pik di tin dɛn we yu de yuz fɔ tek tɛm pikchɔ, di prayz nɔmɔ nɔ fɔ bi di tin we go disayd. Wan tɛmal kamɛra wit ay rizɔlt ɛn lɔwa NETD de kɔst mɔ, bɔt i de detekt mɔ ali anomaly — frɔm di pɔynt fɔ avɔyd di ikwipmɛnt fɔ pwɛl, di ROI fɔ dis invɛstmɛnt rili ay. Di kɔr valyu fɔ divays lɛk di PK63 nɔto di mɛzhɔmɛnt akkuracy — na di abiliti fɔ di mentenɛns tim fɔ fɛn prɔblɛm bifo di ikwipmɛnt trip.
Di wan dɛn we de bay fɔ pe atɛnshɔn bak to di ditil dɛn we i izi fɔ fɔgɛt na di makɛt matirial dɛn: if di divays de sɔpɔt data ɛkspɔt (fɔ intagret wit mentenɛns manejmɛnt sistɛm dɛn); if i de sɔpɔt vidio rikodin (fɔ dinamik prɔses analisis); if bateri layf mit wan ful de fɔ yuz na fil; ɛn if i de sɔpɔt kɔntinyu fɔ wok na say dɛn we gɛt ay tɛmpracha.
