MTF - Continuous Foil Thickness Gauge

This gauge is designed for precision continuous online measurement of metal foil thickness. Types: MTF-150, MTF-250.

MTF-150

The gauge sliding in the operating position on strips is carried out by SIEMENS automatic drive using pneumatic system. The design of the diamond contacts, which are permanently touching the measured strip, secures they do not impair the appearance of the material and have long service life. The pneumatic thrust of the contacts on the strip can be continuously controlled.

This continuous gauge was developed as an absolute measuring device requiring no mechanical readjustment for the nominal thickness of the measured strip and its absolute measuring capability allows to use it also for precision calibration of other (e.g. contactless) gauges during the production process.

The control unit enables:

  • REFERENCEdigital thickness on 7" touch panel display
  • bar graph to show the deviation from the set nominal thickness
  • setting and monitoring lower and upper limits
  • digital calibration of the gauge
  • anlogue outputs for AGC ±20 mA (± 10V; 4-20 mA)
  • serial data output PROFINET (PROFIBUS...)
  • control of moving head into strip line

Features:

  • absolute digital display of the measured thickness
  • independence of the measured material type
  • no mechanical adjustment of the gauging head for nominal thickness
  • easy operation
  • 5 years warranty on diamond contacts

Optional accessories:
