Control of basis weight / thickness

Transmission of beta rays

The weight monitoring and control system measures the weight continuously, without contact, destruction-free and on moving product. The measurement is based on the attenuation of rays from a radioactive isotope through the substrate located in the measuring gap. This attenuation in intensity is an indication of the weight of the product.

Product highlights

  • Highest repeatability ofthe measured values
  • Non-contacting measurement
  • Digital signal processingTemperature compensation
  • Source ageing compensation
  • Gap compensation

Customer benefits

  • Material saving
  • Quality assurance
  • Increased production
  • Comprehensive quality documentation

Optimal basis-weight set-point

The correct basis weight is a decisive quality criterion in many process technologies in the textile industry and coating technology. Monitoring, control and logging of this parameter is therefore a decisive process step. The key is to determine the basis weight under the given industrial conditions online and with high repeatability.

In addition to ensuring product quality, an appropriate set-point with narrow tolerances can provide considerable savings in material and energy consumption, achieve process reliability while at the same time increasing production.
