Qhov zoo thiab kev siv ntawm cov ntsuas kub tsis sib cuag infrared thiab cov thermocouples
Infrared ray yog ib hom electromagnetic yoj, uas muaj tib lub ntsiab lus raws li xov tooj cua yoj thiab pom lub teeb. Nws wavelength yog nyob nruab nrab ntawm 076-100μm.
Txhua yam khoom uas muaj qhov kub siab tshaj qhov xoom xoom (-273.15K degree) yuav tsis tu ncua radiate infrared rays mus rau qhov chaw nyob ib puag ncig vim lawv tus kheej molecular motion. Qhov loj ntawm cov khoom lub zog hluav taws xob infrared thiab nws qhov kev faib tawm los ntawm wavelength muaj feem xyuam rau nws qhov kub thiab txias muaj kev sib raug zoo heev.
Tus pas ntsuas kub infrared emits infrared hluav taws xob hluav taws xob los ntawm kev ntsuas lub teeb siv ntawm cov khoom, thiab hloov nws mus rau hauv lub teeb liab hluav taws xob ntawm lub ntes los ntawm kev kho qhov muag. Qhov kub ntawm qhov khoom yog xam raws li qhov loj ntawm lub teeb liab hluav taws xob. Tus pas ntsuas kub infrared ua rau tag nrho cov txheej txheem ntsuas kub. Kev ntsuas tsis sib cuag, tseem hu ua "tsis sib cuag infrared tus pas ntsuas kub".
Technical zoo ntawm infrared tus pas ntsuas kub:
High precision: Xaiv cov lo ntsiab muag kho qhov muag zoo tshaj plaws, nrog rau qhov emissivity ruaj khov ntawm 0.95, qhov kev daws teeb meem kho qhov muag ntawm 15: 1, thiab lub sijhawm teb ntawm 500ms (95%) txhawm rau tshawb xyuas qhov hloov pauv me me hauv qhov kub thiab ntsuas cov khoom. nrog siab precision, 4 ~ 20mA tso zis Lub teeb liab yog ruaj khov dua.
Yooj yim rau nruab: Cov khoom siv yog kev sib xyaw ua ke, ruaj khov, hnav thiab yooj yim rau nruab. Cov qauv xov ntawm lub plhaub hlau tuaj yeem txuas tau sai rau qhov chaw teeb tsa, ua kom yooj yim rau nruab thiab siv.
Kev tiv thaiv qib siab: Tus pas ntsuas kub infrared siv 24VDC ua haujlwm voltage thiab qib tiv thaiv yog IP65. Nws tuaj yeem siv rau ntau qhov chaw ua haujlwm hnyav, ua rau kev saib xyuas kev ua haujlwm yooj yim dua thiab nyab xeeb dua.
Cov ntsuas kub infrared tuaj yeem ntsuas qhov kub ntawm cov khoom xws li castings, furnace temperatures, machine parts, glass, room temperature, human body, thee, power systems, etc., thiab tau siv dav hauv kev lag luam, kev tsim kho, kev lag luam thiab lwm yam lag luam.
