Gravimat FMI-15
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.
