Valmet IQ Virtual Sensor gives paper and board producers real-time visibility of critical end-product strength properties.
April 7, 2026 - Valmet is introducing Valmet IQ Virtual Sensor, a software-based solution that gives paper and board producers real-time visibility of critical end-product strength properties that have traditionally been measured only in the laboratory. By providing continuous quality predictions, the solution enables mills to maintain consistent quality, reduce fiber and starch costs, decrease energy consumption, and increase overall production efficiency.
By delivering minute-by-minute predictions of key paper properties, such as tensile and tear strength, burst and short-span compression test (SCT), using the mill's existing data, the system provides operators with real-time visibility into product quality. Continuously learning from laboratory feedback, it enables proactive process optimization, reduces waste, helps prevent quality deviations, and ultimately improves mill profitability.
"To avoid rejected batches, operators frequently build in large safety margins, resulting in increased use of costly raw materials and higher production costs," explained Timo Aro, Business Manager, Quality Management System, Automation Solutions, Valmet. "With Valmet IQ Virtual Sensor, operators no longer need to wait for laboratory results to understand how their actions will affect end-product quality.
"In addition, its built-in 'what if' simulator lets operators test adjustments and see predicted impacts before applying changes to real production. By reducing uncertainty and enabling lower safety margins, the solution demonstrates how optimized process control helps unlock resource efficiency," Aro said.
Valmet IQ Virtual Sensor delivers real-time quality predictions during processing without the need for additional sensors or production downtime. All calculations run locally, without cloud dependency, ensuring secure data handling and fast response times.
In addition, IQ Virtual Sensor is future-proof and can be expanded to automated closed-loop controls with Valmet Advanced Process Controls (APC), enabling the next level of quality performance, process optimization, and profitability.
