Prinċipji ta' Infrared Termometri _ Kalibrazzjoni ta Infrared Termometri
Infrared temperatura kejl teknoloġija drammi an rwol rwol in prodott kwalità kontroll u monitoraġġ, tagħmir online fault dijanjosi u sigurtà protezzjoni, u enerġija konservazzjoni tul il-produzzjoni proċess. Imqabbel biex kuntatt temperatura kejl metodi, infrared temperatura kejl kampjuni temperatura kampjuni bħal fast response time, non-contact, safe use, and long service life. So, what is the principle of an infrared termometru? What should be noted when using?
Il-prinċipju ta an infrared termometru is kif ġej:
1. Prinċipju infrared
Any object with a temperature higher than absolute zero (-273 degree ) emits thermal radiation to the outside. The energy emitted by an object varies depending on its temperature, and the wavelength of the radiation also varies. However, it always includes infrared radiation. Objects below a thousand degrees Celsius have strong electromagnetic waves in their thermal radiation, li are infrared waves. Għalhekk , kejl l- infra-aħmar radjazzjoni ta ' l-oġġett innifsu jista' b'mod preċiż jiddetermina its wiċċ temperatura. Dan huwa l- objettiv bażi għal infrared termometru temperatura kejl.
2. Prinċipju tax-Xogħol
Il- non-contact infrared termometru jikkonsisti of an optical system, a photodetector, a signal amplifier, signal processing, display output, and other components. The optical system gathers the infrared energy emitted by the target object, focuses it on the photodetector, and converts it in the photodetector, and converts it in the corresponding electrical signal. After being processed by the circuit, it is converted in a linear temperature signal value of the measured target, in order to achieve further signal processing and control.
Kalibrazzjoni passi ta ' infrared termometru
Fi il-produzzjoni proċess, infrared temperatura kejl teknoloġija plays an important role in product quality control and monitoring, equipment online fault diagnosis, safety protection, energy conservation, and other aspects. In the past 20 years, non-contact infrared termometri have developed rapidly, with improved performance, continuously enhanced functions, an increasing variety, and an expanding range of applications. Compared with contact temperature measurement methods, infrared temperature measurement has advantages such as fast response time, non-contact, safe use, and long service life. The non-contact infrared termometer consists of three series of portable, online scanning, multiple options, and computer software, each with multiple models and specifications. Huwa ħafna importanti għal utenti biex tagħżel il korrett infrared termometru fong diversi speċifikazzjonijiet ta ' termometri.
Il- kalibrazzjoni passi għal an infrared termometru huma kif isegwi:
Skond to it-temperatura kejl firxa , post a metall materjal kampjun bi a dijametru akbar minn il - ... meħtieġa infrared termometru dijametru in il reżistenza forn. Test il imsemmi hawn fuq standard tip S prezzjuż metall thermocouple, użu it-termokoppju kif ir-referenza temperatura sors. Biex tiżgura il - qarib stabbiltà ta ' it-temperatura sors 2c l- espansjoni inċertezza ta' ir-referenza kalibrazzjoni temperatura sors m'għandux ma jaqbeż it-tabella .
Kalibrazzjoni metodu: Kalibrar l ambjent kundizzjonijiet, ambjentali temperatura (18-25) C reference standard, u l umdità of the working environment of the electrical measurement device should be consistent with it.
Tekniċi rekwiżiti huma meħtieġa.
Relative humidity:>85%, evita b'saħħtu sfond radjazzjoni u jalterna oqsma manjetiku .
Appoġġ faċilitajiet: Il preċiżjoni ta ' l- standard temperatura sors (ikkonvertit għal temperatura) għal tip S thermocouples u tagħhom kejl punt tagħmir għandu ikun aħjar minn 1% 2f10 ta ' il - massimu permess żball ta' l-infrared kejl strument.
L- insulazzjoni reżistenza metru ma a rata vultaġġ ta' 520V ġie ikkalibrat.
Il- digital display must be clear and complete, and the buttons must be normal. When the battery is low, it can be calibrated after replacing the battery.
Kalibrazzjoni riżultat ipproċessar : Il kalibrazzjoni data ipproċessar huwa ibbażat fuq l - implimentazzjoni ta ' il sħiħ radjazzjoni termometru verifika regolamenti. Il kalibrazzjoni proċess huwa irreġistrat fuq l-infrared termometru kalibrazzjoni rekord form% 2c u il - kalibrazzjoni rapport huwa mimli wara il - kalibrazzjoni huwa lest.
