Infrared Moisture Analyzer Online Determination Principle (1) Absorption Principle Near-infrared rays refer to electromagnetic waves with wavelengths between 0.78 and 2.52 μm. Various electromagnetic waves have a certain amount of energy. The ability of various substances to selectively absorb energy from electromagnetic waves. In other words, a molecule can only absorb electromagnetic waves of one or several wavelengths but not other wavelengths of electromagnetic waves.
The on-line near-infrared moisture analyzer works on the principle that water molecules absorb particularly near-infrared light at certain wavelengths. Water molecules have characteristic absorption peaks in the near-infrared Han region. Water molecules absorb strongly near-infrared light. If the measured substance is irradiated with near-infrared light of these two wavelengths, the moisture of the substance can be measured by measuring the degree of attenuation of transmitted light or reflected light.
(2) Working principle Near-infrared moisture meters use high-precision infrared filters mounted on the wheels, imported motors, allowing reference light and measurement light to alternately pass through the filters. The retained beam will focus on the sample under test. The first is that the reference light is projected on the sample, and then the measurement light is projected on the sample. The two time-sequential light energy pulses are reflected back to one detector and converted into two electrical signals in turn. The two signals combine to form a ratio, because the ratio is related to the moisture content of the material and the moisture can be measured.
The advantages of on-line moisture meter (1) High measurement accuracy, non-contact measurement, more accurate measurement results.
(2) Extremely penetrating - full spectrum white light, so it can penetrate up to 12mm below the surface for measurement.
(3) Any damage to the material - The infrared of the online NIR moisture meter has no effect on the surface color and composition of the material.
(4) The principle of simple and advanced technology - the use of the original light exposure material, so that 100% of the infrared light is irradiated to the material, increasing the overall number of effective energy, the system is not easily affected by color, environment, dust and distance.
(5) Sensors dissipate heat extremely fast - The corrugated surface of the sensor increases the surface area and quickly dissipates heat.
(6) Anti-vibration - Two fixed reflective environments are adopted, which will not affect the measurement results with the jitter of the working environment.
(7) simple maintenance - good after-sales service, excellent quality.
(8) The light is not affected - the original light is ensured, and the wavelength of the light that causes the water molecule to resonate is retained. After such irradiation, the material resonates and the device is not affected by the light (9) The use of the head circuit is imported. High-speed processing chip and digital gain chip, imported motor, high precision filter.
(10) The head program is more intelligent and has status indicators.
(11) The probe is fully cast aluminum housing and can be equipped with air cooling device.
