CWH900-1450 Explosion Proof Infrared Thermometer Technology Analysis G&D Electronic Technology In 1672, it was found that sunlight (white light) is composed of various colors of light. At the same time, Newton made a monochromatic light that is better than white light in nature Simpler conclusion. Using a dichroic prism, the sunlight (white light) is decomposed into monochromatic lights of red, orange, yellow, green, cyan, blue, and purple. In 1800, British physicist F. W. Huxel discovered infrared light when he studied various colored lights from a thermal point of view. When studying the heat of various colored lights, he deliberately blocked the window of Weiyi in the dark room with a dark plate, and a rectangular hole was opened in the plate, and a dichroic prism was installed in the hole. When sunlight passes through the prism, it is decomposed into colored light bands, and a thermometer is used to measure the heat contained in the different colors in the light band. In order to compare with the ambient temperature, Huxell used several thermometers near the colored light band as comparison thermometers to measure the ambient temperature. In the experiment, he accidentally discovered a strange phenomenon: a thermometer placed outside the reddish light is higher than the indication value of other temperatures in the room. After trial and error, this so-called high-temperature high-temperature region is always located outside the red light at the edge of the light band. So he announced that in addition to visible light, there is a "re line" invisible to the human eye. This invisible "re line" is located outside the red light and is called infrared light. Infrared is an electromagnetic wave that has the same essence as radio waves and visible light. The discovery of infrared is a leap forward in human understanding of nature, and it has opened up a whole new broad road to the research, utilization and development of infrared technology.
Infrared has a wavelength between 0.76 and 100μm, and can be divided into four categories: near infrared, mid infrared, far infrared, and far infrared according to the wavelength range. Its position in the continuous spectrum of electromagnetic waves is between radio waves and visible light. . Infrared radiation is a kind of extensive electromagnetic wave radiation that exists in nature. It is based on the fact that any object will produce its own random movement of molecules and atoms in a conventional environment, and it will continuously radiate thermal infrared energy, the movement of molecules and atoms. The more intense, the greater the radiated energy, and conversely, the smaller the radiated energy.
CWH900-1450 explosion-proof infrared thermometers whose temperature is above zero degrees will radiate infrared rays due to their own molecular motion. After the power signal radiated by the object is converted into an electrical signal by the infrared detector, the output signal of the imaging device can completely simulate the spatial distribution of the surface temperature of the scanned object in a one-to-one correspondence, processed by the electronic system, and transmitted to the display screen to obtain and The thermal image corresponding to the heat distribution on the surface of the object. Using this method, it is possible to achieve long-distance thermal image imaging and temperature measurement of the target, and to analyze and judge.
CWH900-1450 Explosion-proof Infrared Thermometer uses explosion-proof infrared thermometer to measure temperature in infrared non-contact mode. The infrared light spot can be measured instantly on the target under the environment. It is fast and safe to use.
