▼Measurement index

Water content (%), quantitative (g / m2), film thickness (μ m), coating material coating quantity (g / m2), organic matter component content measurement (%).

▼Application area

Paper, film, all kinds of coating adhesive tape, film functional coating, organic sheet.

▼Mainly constitutes

The multi-wavelength you infrared component sensor consists of the transmitter head and the receiver head.

The emission head mainly includes: the emission head box, halogen light source, light source adjustment circuit board, light guide cylinder, convex lens and so on.
The receiving head mainly includes: receiving head box, multi-channel branch flexible optical guide fiber, filter, infrared detector, signal transport and discharge circuit board, communication circuit board, etc.

▼Measuring principle

The material component has a strong absorption capacity of the infrared energy at a specific wavelength, without absorbing the infrared energy at other wavelengths. The wavelength that is easy to be absorbed by the material component is selected as the measurement wavelength and the material wavelength as the reference wavelength, and the ratio of the measured wavelength and the reference wavelength to the actual content of the measured material is established, and the component content of the measured material can be selected. The detection object of different content has the corresponding characteristic wavelength filter configured to achieve the accurate measurement of each component.

▼Technical characteristics

◆ light source soft start power supply, pulse width modulation of current stability and protection circuit, stability, energy saving, durability;

◆ measures the clearance of multiple reflection transmission structure, and the detection sensitivity is higher;

◆ multi-detector detection at the same time as the same view point, the signal ratio has no disparity time difference, adapt to fast scanning;

◆ can measure the content of four components at the same time to improve the accuracy of the comprehensive index;

◆ cut disc and other rotating parts, more reliable work, multi-optical continuous measurement rather than alternating measurement;

◆ infrared detector aDOpts photovoltaic devices, no dark current, better thermal stability and linearity;

◆ optical intensity signal output mode 4~20mA or 0~10V is optional, the probe temperature signal current output;

◆ near-infrared band measurement, fully shielding the influence of environmental light source;

◆ pre-calibration samples and data are sufficient, mathematical graphics software fitting, the function curve is closer to the true measurement;

◆ constant temperature heating air dryer options, air gap temperature is controlled to prevent window condensation.
