Valmet launches new microwave consistency measurement for pulp and paper makers

Espoo, Finland - Valmet has redesigned its Valmet Microwave Consistency Measurement (known as the Valmet MCA) for the pulp and paper industry.

Valmet MCA is a third generation microwave consistency transmitter. The latest electron ics and redesigned mechanical construction provide even greater reliability, easier installa tion and the tremendous accuracy of the microwave measurement principle. The Valmet MCA measures total consistency independent of pulp grade, recipe or production speed – for optimized paper production and quality.

“This new measurement technology is a leap forward in terms of performance and usability. For long Valmet has been the market leader in microwave consistency measurements with more than 6,000 deliveries. The new Valmet MCA now leads the way for all pulp and paper needs,” said Marko Heikkinen, Valmet’s product manager, automation business line.

The new MCA features digital electronics and the new direct sweep detection measurement to offer higher performance measurement sensitivity and accuracy than competing analogue designs.

Valmet MCA measures total consistency of the pulp process stream independent of fibre length, freeness, wood species or blend. The measurement is not affected by flow rate, brightness or colour and enables better control for more efficient production, improved quality and economic savings with fewer process upsets and less off grade product. With low lifetime costs, the sensor is simple to install and requires no regular maintenance to keep commissioning and running costs to a minimum.

Valmet MCA’s new twin blade sensor complements the offering, along with the newlyredesigned flow through sensor, by allowing paper and pulp makers to install it in larger pipe diameters. The flowthrough sensors are totally interchangeable with earlier installations.

With a wider applicability, the new twin blade sensor can also be used to measure unscreened pulp. The sensor’s completely redesigned clamp mounted probe is suitable for the much higher conductivity environment of chemical pulping.

Commissioning and operation have also been enhanced with the Valmet bridge user interface, a new seven-inch, touch screen control platform designed for use with Valmet process sensors and analyzers. With comprehensive diagnostics, Wi-Fi and Industrial Internet ready capabilities, Valmet bridge user interface provides a user-friendly experience and intuitive access to transmitter operation and remote services from Valmet.
