Fiber optic visible spectrometer system for measuring transmission / absorption of liquids

Example Transmission System

This is an example versatile and expandable system is well suited for measuring the NIR transmission of liquids.

Potential Applications

  • Inline moisture & protein monitoring in grain-processing or food-drying lines—mount the tiny USB-powered module directly on conveyers for real-time QA.
  • Polymer and resin cure tracking on production extruders—embed the spectrometer in a closed-loop control system to follow chemical conversion and adjust oven residence time instantly.
  • Blend uniformity monitoring in pharma mixers—mount the sensor on a viewport and stream spectra to verify API homogeneity long before compression.
  • Real-time lubricant degradation analysis for predictive maintenance—track oxidation and additive depletion in hydraulic oils on rotating machinery.• Rapid resin identification in plastics recycling—sort PET, HDPE, PP, and nylon on high-speed conveyor belts by their NIR fingerprints.
  • Inline moisture & lignin assessment during wood-pellet production—optimize dryer energy use and meet fuel-grade specs.
  • On-farm forage quality testing—attach to a handheld probe to estimate protein, fiber, and dry matter in silage within seconds.
  • Sugar-cane or beet processing control—measure Brix and sucrose purity continuously to maximize extraction efficiency.
