M300 near red moisture meter
The near-infrared on- line moisture analyzer collects near-infrared beams of multiple wavelengths on the surface of the measured object, and the near-infrared beams reflected on the surface are received and processed by an advanced infrared optical detection system. This advanced infrared optical detection system can quickly process data. An embedded ultra-performance miniature digital signal processing chip is used to process, store and display the required data, and its accuracy and stability are outstanding.
The principle of infrared light absorption The molecular structure inside a substance, such as the oxygen-hydrogen bond in water and the carbon-hydrogen bond in organic matter, will absorb near-infrared light of a specific wavelength. At a specific wavelength, the reflected near-infrared energy is inversely proportional to the number of molecules it contains that absorb near-infrared rays. On-line moisture measurement is based on the principle that near-infrared wavelengths are absorbed by water molecules, and analyzes changes in near-infrared energy at a specific wavelength.
Composition of M-300 online infrared moisture analyzer: M-300 is a high-configuration online moisture analyzer upgraded on the basis of M-100. The instrument adopts a dual-core design, and the main components are a near-infrared probe and a display.
Near-infrared probe: Imported light-guided PBS detector is used. The detector is packaged independently. The external light does not interfere with the reference measurement; the reference measurement light of the optical path structure and the product measurement light use the same optical path to eliminate the influence of detection errors. The probe has a built-in single-chip microcomputer for signal analog-to-digital conversion, which avoids the problem that the optical signal is easily interfered by the analog signal transmission. The probe uses DC24V power supply and low voltage is safer. These can improve the measurement accuracy and stability of the near infrared moisture meter.
The display adopts an industrial touch screen, which can switch between Chinese and English display, with graphical curve display, up to 6 months of history, and the USB interface supports data export and software upgrade functions. The host also has analog quantity (DC4-20MA), digital output (MODBUS-RTU, MODBUS-TCP), and digital signal (two passive contacts). The signal output is more flexible and convenient,
The M-300 online near-infrared moisture meter is mainly used in industries with high-end requirements, such as steel ore, food and other industries. The M-300 probe signal is transmitted using a digital protocol. The distance between the probe and the human-machine interface can be up to 50 meters. , It is suitable for the working condition where the measured moisture point and the distance between workshops are far.
