What is infrared radiation?
Infrared thermometers are operated by infrared radiation. Infrared is part of the electromagnetic spectrum that occupies visible light. The electromagnetic spectrum is a set of different types of radiation. It includes gamma rays, X -rays, ultraviolet rays, visible infrared radiation, microwaves, and radio waves. The wavelength of infrared light is greater than the wavelength of visible light. Therefore, infrared light is invisible light. "Infrared" means "below the red line", indicating that this light can only be seen below the red of the electromagnetic spectrum.
Features
The LDX-300 non-contact temperature sensor produced by Beijing Lande Meike can measure the infrared energy released by all target objects and has a fast response. It is commonly used to measure moving and intermittent targets, targets under vacuum, targets that cannot be contacted by humans due to space limitations in harsh environments and security threats. Although it can be done using other equipment in some cases, the cost is relatively high.
Contact and non-contact temperature measurement
The contact temperature detector must be commensurate with the target material temperature. For example, mercury in a glass thermometer receives the temperature in the air and therefore expands or shrinks. When a contact detector is placed in a different environment, it will take some time to adapt to the new environment. This is also called the detector's response time. At some application sites, it is impractical or impossible for the detector to come into contact with the analyte. The infrared detector can measure temperature at a long distance in a short time, so it is very practical in some cases.
Temperature measurement principle
The infrared detector converts the absorbed radiation into heat energy, thus increasing the temperature of the detector. And the temperature change data into electronic signals, zoom out.
Radiation principle
All objects are made up of constantly shaking atoms, and the higher the frequency of high energy atomic vibrations is. The vibration of all particles, including these atoms, generates an electromagnetic spectrum. The higher the temperature of an object, the faster it will vibrate and the higher the radiant energy of the spectrum. As a result, all objects are constantly radiating at their own wavelength and frequency, which in turn depends on the temperature of the object itself and its spectral emissivity.
Ratio of visual range to distance to diameter
The visual range refers to the angle of operation of the instrument, which is determined by the diopter of the individual. The visual range is the ratio of instrument and target distance to target diameter. The smaller the target, you should rely on it closer. When the diameter of the target is very small, it is important to put the thermometer closer to the target. This ensures that the target is measured only and does not include the surrounding environment.
Laser visible
The laser spot is used to display the point of the measurement area, rather than emitting something to measure. This is a misunderstanding. The sensor is placed next to the laser module and is directly illuminated. The same light path is formed with the laser.
