IR Moisture Sensor

Online surface moisture measurement

Key Features

  • Non-contact, single sided online measurement
  • Liquid cooled head platform for better long-term reliability
  • More accurate online measurements with less calibration needs
  • Dust trap before lens to keep it free from steam and dust
  • More accurate online measurements using large optical components

Measuring Method

The Scienta NIR absorption-based sensor series 7230 is a double sided, 2-channel or 4-channel InGaAs detector-based Moisture weight sensor for online use. The sensor measures the infrared light absorbed by different wavelengths caused by the water on sheet. This signal is digitalized and linearized to correlate to real weights in engineering units. Moisture range is 1 – 35 %. Paper weight range is 5..350 g/m².
