Quality Measurement and Control Systems for Paper Industry

Seltek Quality Measurement and Control Systems (QCS) are used for different applications in pulp and paper industry such as:

  • Tissue
  • Fine Paper
  • Fluting / Testliner
  • Grey Board
  • Duplex Board
  • Filter Paper
  • MG Paper
  • Cement Sack Paper
  • Coat Weight
  • Pulp

These systems measure certain quality parameters of the paper on-line such as:

  • Basis weight (grammage)
  • Moisture
  • Ash
  • Caliper
  • Color
  • Porosity

and so on. Nucleonic, near infrared, microwave, x-ray, etc. principles are used for design of these sensors. Measurements are mostly non-contact type.

O-Frame is the most common scanner used. Single beam scanners and C-Frame scanners are also available.

Electronics enjoy a distributed architecture and the cabling between the frame and the main CPU is minimal, being restricted to Ethernet cable and power cable.

Machine Direction Controls as well as Cross Direction Controls are available.

Profile Control Actuators for:

  • Basis weight,
  • Moisture and
  • Caliper
are application matched.

HMI (Human Machine Interface) is operator friendly. Fast and slow trend plots, profile pages, recipe page, rich maintenance page, controls page, roll report page, alarm and event log pages are all very easy to learn and self guiding. Roll data is stored numerically in MS SQL® database, which can be converted to Excel® format for use by mill staff.
