Calibration of Machine Length Counters

correct roll lengths and coil lengths through regular inspection

Encoders and machine length counters for detecting web lengths or roll lengths should be checked for proper function and accuracy from time to time. This is done quickly and safely with the non-contact μSPEED length measurement systems. The highest possible measurement accuracy, 100% documentation as well as measurement and calibration protocols by a calibration specialist are accompanied by the subsequent assurance that the roll lengths and coil lengths are measured correctly.

Typical application data:

  • Path Velocity: typically up to 4,000 m / min
  • Measurement accuracy with tactile measuring equipment or via drive: typically 0.5-5%
  • Measurement accuracy with non-contact length measurement μSPEED: typically 0.03%
  • Amortization: at the first complaint that has been avoided

Measurement and material examples:

  • Inspection of length meters of winding machines for paper, cardboard, tissue, foil, floor coverings, sheets, coils, textiles, wire, cables, profiles, …
  • Inspection of counters for transparent foil, glossy foil, food foil, packaging foil, furniture foil, …
  • Troubleshooting to find equipment with slippage, elongation, shrinkage, …

Machines equipped with non-contact length measurement:

  • roll cutting machines, roll cutter, cross cutter, lengthwise cutter
  • Winding machines, rewinder, re-roller, doctor roller
  • extruders, film casting machines, calenders
  • laminating machines, fabric inspection machines
