Main features and advantages
The technical characteristics and competitive advantages of Valmet Met-818149 are reflected in the following dimensions:
1.High-precision spectral analysis and multi-component detection
Equipped with a high-resolution spectrometer(Spectrometer,wavelength range of 700-2500nm),it can detect up to 20 components(such as moisture,fat,protein,ash,etc.)simultaneously,with an analysis accuracy of±0.1%.Supports quantitative analysis of complex matrix samples(Quantitative Analysis)and is suitable for multivariate process control.
2.Real-time spectral modeling and adaptive calibration
The dynamic spectral model is constructed through the PLS(Partial Least Squares)algorithm and the correction coefficients are updated in real time.Built-in Adaptive Calibration System(Adaptive Calibration System)automatically compensates for light source attenuation,temperature drift and sample morphology changes to ensure long-term stability.
3.Millisecond level response and closed-loop control
The detection period is as short as 200ms,supports PID(Proportional-Integral-Derivative)control protocol,and adjusts upstream process parameters(such as feed rate and temperature settings)in real time.Seamless integration with DCS(Distributed Control System)to achieve multivariate linkage control.
4.Predictive quality analysis and process optimization
Based on the machine learning model(Machine Learning Model),we warn of quality deviations(such as concentration exceeding the standard and abnormal composition)15 minutes in advance.Supports correlation analysis of process parameters and product quality,optimizes formula adjustment and energy consumption management.
5.Contactless design and extreme environmental adaptability
It uses Fiber Optic Probe and IP67 protective shell,suitable for high temperature(to 200°C),high pressure(to 30MPa)and corrosive media.The anti-electromagnetic interference(EMI)design complies with IEC 61000-4-3 standard to ensure signal stability.
