Il-prinċipju ta ' termometru
A termometru huwa a tip ta ' termometru li juża il-prinċipju ta infrared trasmissjoni ta ' numri sens il wiċċ temperatura ta' oġġett Huwa relattivament faċli biex topera, speċjalment għal kejl temperatura għolja oġġetti. Widely used, tali azzar ikkastjar, forn temperatura, magna partijiet , ħġieġ u kamra temperatura , korp temperatura u oħra wiċċ temperatura kejl ta ' diversi oġġetti. L l-aktar komunement użat wieħed huwa il infrared termometru.
Infrared termometru jikkonsisti of optical system, photoelectric detector, signal amplifikatur, signal processing, display output and other parts. The optical system gathers the target infrared radiation energy within its field of view. The size of the field of view is determined by the optical parts of the termometer and their positions. The infrared energy is focused on the photodetector and converted a corresponding electrical signal. Is-sinjal jgħaddi jgħaddi minn l-amplifikatur u sinjal ipproċessar ċirkwit, u is ikkonvertit f' it-temperatura valur ta' il imkejjel mira wara korrezzjoni skont l-algoritmu ġewwa l-istrument ubriju u il-mira emissività.
Id-differenza bejn industrijali termometru u mediku termometru
Whether it is a medical or industrial infrared thermometer, its principle is to receive infrared waves emitted by the human body. Industrial infrared thermometers measure the surface temperature of the human body. The normal human forehead temperature is about {{0}} degree lower than the armpit temperature, and the forehead changes greatly due to environmental influences. Therefore, armpit body temperature is used as a medical temperature measurement in clinical medicine. Before leaving the factory, the medical thermometer has revised the difference or limited the relevant range through software. Industrial products provide more realistic feedback on temperature measurement conditions. The emissivity of the normal human body is 0.98 (the thermometer defaults to 0.95), so the measured result is around 34-35 degree . The BG45R product can correct the difference by modifying the emissivity to 0.98 to avoid inaccurate body temperature when used by non-professionals.
(Nota: The forehead is greatly affected by the environment, so it is only for reference for preliminary troubleshooting. The principle is the same whether it is a medical or industrial detector. I hope it will be helpful to everyone.)
