Infrared sensors

Infrared transmission / reflection – Measurement of moisture, basis weight, thickness

By means of optical evaluation of the reflected light energy in the near-infrared range (NIR), important product-specific parameters such as moisture (water), coating weight, thickness, and organic components in the web can be measured during the manufacturing process.

Its non-nuclear measurement technique is very selective and offers an accurate and cost-effective measurement solution that can be supplied in either single-sided reflection, or dual-sided transmission modes.

Infrared pyrometer

The product temperature at the dryer delivery depends on the residual moisture. To determine the residual moisture the surface temperature of the product is measured at the outlet of the dryer using a high-temperature resistant infrared pyrometer without contact. The dryer speed is automatically adapted.

Product Highlights

  • Non-contacting product temperature measurement
  • High-temperature rated sensors
  • Little assembly and maintenance effort
  • Self-cleaning sensors

Customer benefits

  • Highest repeatability
  • Optimal utilisation of the stenter capacity
