Working Principle:
1. The hydrogen-oxygen bonds in water molecules absorb near-infrared rays of a specific wavelength. At a specific wavelength, the reflected near-infrared energy is inversely proportional to the near-infrared energy absorbed by the water molecules in the material. The moisture content of the measured material is calculated based on the amount of energy loss.
2. When water molecules are excited by a specific energy band, they become vibrational states. In the near-infrared part of the spectrum, this band is particularly strong for water molecules, and the instrument is easier to achieve in terms of emitting, filtering and receiving energy.
3. Near-infrared measurement technology is a non-destructive, non-contact real-time measurement technology.
Structure Features:
1. Adopting single sensor and five wavelengths for detection, its stability is greatly improved compared with six beams and eight beams
2. Five wavelengths, more reference wavelengths for measurement, making the measurement stability and measurement accuracy better
3. The average test accuracy can reach about 0.1%-0.5% (depending on the material being measured), meeting the production process requirements
4. Realize online dynamic real-time detection, the response time is only 8ms, and the real-time control of the moisture content of the product is realized
5. Highly integrated electronic devices, SMT technology circuit boards, low failure rate, stable and reliable quality
6. The filter is smaller than that of traditional brands and is less affected by bandwidth
7. Single lead sulfide sensor, avoiding the problem of different linearity of dual sensors
8. Dynamic real-time diagnostic system, no need for regular maintenance
9. More output signal modes, RS485, 4-20mA analog signal and RS232
Function Features:
1. Non-contact, using infrared technology to measure moisture in diffuse reflection mode
2. Multi-channel setting, SY-300 series moisture meter has 10 channels, numbered from 1-10, each channel number represents a set of the above channel parameters, changing the channel number, that is, selecting different channel parameters to meet the needs of the same instrument to measure different types of materials
3. Basically not affected by external light changes, with automatic temperature compensation, basically not affected by external temperature changes, good long-term stability
4. Simple installation, convenient and fast operation, and normal production will not be affected during installation and debugging. SY-300HW series moisture meter adopts pre-calibration, and the calibration work can be completed on site by simply correcting the intercept (zero position)
Application Fields:
Steel industry: sintering mixture, pellet raw materials, before and after drying, pelletizing, etc.
Nonferrous metals: bauxite, copper concentrate, mineral sand, nickel ore, gold, silver, lead and zinc concentrate, alumina and nonferrous smelting, etc.
Tobacco industry: cigarette packs, tobacco stems, tobacco leaves, tobacco shreds, redrying, tobacco branches, etc.
