Online thickness measurement solutions

We are specialists in the online measurement of thickness and density on flat products, no contact and directly during the process. Our systems are the ideal solution as input for automatic gauge control, providing accurate, fast and reliable data output as input reference for the automation process control. 

Key features

  • Signal transmission: fully digital
  • Response Time: from 100 microseconds
  • Accuracy : +/- 1/1000 of the target thickness
  • Stability and drift: 0.1% in 10 hours base

Thickness of flat metals

Extremely accurate measurement of the thickness along the strip length. 1 set of sensors is required.


3 points scan Thickness and profile measurement

Centerline and border on demand cross profile scanning along the width. 3 set of sensors is required.


Continouos profile scanning Thickness & profile measurement

Continous scanning with moving sensors along the width and centreline scanning. 1 set of sensors is required.


Thickness related variables Edge drop, wedge and crown

Scanning solutions ideal for edge drop and crown evaluation, cross shape profile of a flat product useful to perfectly set up the rolls.

Coating thickness

Our coating measurement system can measure continuously and online during process different nature of coatings:

  • zinc
  • zinc and iron
  • zinc and aluminium

Density and inconsistency

Enhanced accuracy & dependability solution to inspect material's density and inconsistency. Flexible PLC-based design using widely available off-the-shelf components.

Online data mining

Each system is suitable to securely store data and provide work reports, built with cross referenced data deriving from several process variables such as speed, vibrations and thickness.

Post process statistics

From traditional analysis of variance and linear regression to inference and high-performance modeling methods for massive data analysis.

Data storage and presentation

Secure storage capability to centrally managed servers ensuring wide capacity and appropriate performance for different types of data and cross referenced analysis results stored in wide used database formats, ensuring the complete process knowledge at the mouse click.
