Folding infrared raysmAYTextile Testing Instruments, Testing Equipment Manufacturer


Infrared is a type of light that is invisible to the human eye but is actually an objectively existing substance like any other light. As long as an object has a temperature above thermodynamic zero, it radiates infrared rays into the environment. mAYTextile Testing Instruments, Testing Equipment Manufacturer


Infrared rays are rays other than red light in visible lightand are therefore called infrared rays. Its wavelength range is approximately in the spectral range from 0.75 to 100 μm. mAYTextile Testing Instruments, Testing Equipment Manufacturer


Folding infrared radiationmAYTextile Testing Instruments, Testing Equipment Manufacturer


The physical nature of infrared radiation is thermal radiation. The higher the temperature of the object, the more infrared rays it emits and the er the infrared radiation energy. mAYTextile Testing Instruments, Testing Equipment Manufacturer


The study found that the thermal effect of various monochromatic lights in the solar spectrum gradually increases from violet light to red light, and the thermal effect occurs in the frequency range of infrared radiation, that is, infrared radiation is also called thermal radiation or called heat rays. mAYTextile Testing Instruments, Testing Equipment Manufacturer

Folding sensor principlemAYTextile Testing Instruments, Testing Equipment Manufacturer

The thermal sensor uses the radiant heat effect to increase the temperature of the detecting device after receiving radiant energy, and then increase a portion of the sensor. The performance of the beam varies with temperature. mAYTextile Testing Instruments, Testing Equipment Manufacturer


Radiation he cancan be known by detecting a change in one of these properties. In most cases, the radiation is captured by the Seebeck effect. When the device receives the radiation, a non-electrical physical change is caused, and it can also be measured by converting it to an electrical quantity through a corresponding change. mAYTextile Testing Instruments, Testing Equipment Manufacturer


The thermal sensor uses the radiant heat effect to raise the temperature of the detection device after receiving radiant energy, which changes the output of the column and the temperature in the sensor. By detecting a change in any of these properties, radiation can be detected. mAYTextile Testing Instruments, Testing Equipment Manufacturer
