Weighing controller GRAVIMAT FMI-15

Control of basis weight / thickness Gravimat FMI Basis weight (weight per unit area) measurement and control of running webs with beta sensor 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 of the 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 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.
