Gravimat FMX-T

Measurement of basis weight (mass per unit area) / thickness

Transmission of X-rays <5 kV

The Gravimat FMX-T permits the contactless and traversing measurement of basis weight (grammage) / thickness of the running product webs over the entire product width.

It measures thin film, nonwovens and other fabric with high resolution, measuring accuracy and absence of flaws.

Low voltage but high accuracy

The Mahlo FMX-T is a low voltage X-ray sensor that measures the basis weight (or calculated thickness) of thin films, nonwovens, and other webs with ultra-fine resolution, accuracy and defect detection.

There are a lot of benefits:

  • Non-Nuclear: X-ray tube works without radioactive isotope emitter and can be turned off
  • X-Ray energy below 5kv and exempt from Regulations!
  • Can measure a large range of thickness down to very thin films
  • Excellent CD resolution for accurate profile control
  • Finely focused measurement spot for very narrow Streak / Die Line / Defect Detection
  • Virtually no measurement noise
  • No water cooling required

Product highlights

  • Non-nuclear
  • Contactless, non-destructive
  • Intelligent sensor with fast onboard micro processing

Customer benefits

  • Non-destructive, continuous measurement of basis weight / thickness
  • High measuring accuracy
  • Low maintenance and low cost of ownership

Area of application

  • Nonwovens
  • Plastic
