The Paper Machine Clothing of each individual position must run at precisely set speeds. But are they really doing that?
Why measure if you can comfortably check the speeds in the control room?
The speeds shown in the Drive Control System (DCS) are calculated values, depending on correct input of the roll diameters and data about the fabric caliper.
To eliminate human DCS input errors or faulty assumptions when troubleshooting the machine, it is best to measure where it matters: on the surface of the rolls and fabrics!
Three good reasons to measure the speed with the RealSpeed
1. Unexpected speed differences cause quality and runnability problems
2. Identify slipping rolls that cause extreme clothing wear
3. Done in minutes; it is easy, quick and reliable
