Irving Tissue installs Valmet IQ Fiber Measurement Sensor on tissue machine #1 in Saint John, New Brunswick, Canada, as the company says in the press release received by Lesprom Network.
For many years, the nuclear basis weight sensor, together with an infrared moisture sensor, were the standard to provide an oven dry basis weight reading for control purposes. Several years ago, Valmet combined fiber weight and moisture in a single non-nuclear sensor, Valmet IQ Fiber Measurement.
"The need for nuclear safety training and licenses are now eliminated, as well as the specialized service and safety requirements for radioactive devices. Installed on tissue machines that use virgin pulp, or recycled furnish, the accurate scan averages and high-resolution CD profiles measured by IQ Fiber provide a solid foundation for machine- and cross-direction oven dry weight controls," says Marko Toskala, Director, Quality Management Solutions, Valmet.
Developed especially for tissue, IQ Fiber uses multi-wavelength infrared detection to selectively measure fiber, water and other sheet components with high frequency across the sheet. As well as significantly reducing the initial investment cost, IQ Fiber users report lower maintenance and cleaning requirements leading to as much as 75% lower total cost of ownership.
Valmet is the leading global developer and supplier of process technologies, automation and services for the pulp, paper and energy industries.
