EMG IMPOC - Online yield & tensile strength measurement

EMG IMPOC - Online measurement of tensile strength and yield strength

EMG IMPOC is a proven magnetic-inductive measuring system for the automatic, non-destructive online determination of the mechanical parameters tensile strength and yield strength of ferromagnetic steel strips. Applications include the production of cold-rolled and surface-finished steel strips, for example in:

  • Hot-dip galvanising plants
  • Continuous annealing systems
  • Tinning systems
  • Continuous pickling lines*
  • Processing lines*
  • Automotive lines

The Benefits of Non-Destructive Testing Methods

Non-destructive testing methods offer significant advantages over traditional destructive approaches for determining tensile strength and other mechanical properties of materials.

To carry out the conventional tensile test, production must be stopped so that material samples can be taken first. When carrying out the tensile test, the tensile stress is then gradually increased until it reaches the breaking strength. This permanently deforms or destroys the sample.

In contrast, non-destructive testing methods allow for tensile strength determination without compromising the integrity of the tested component or material.

The measuring principle of the EMG IMPOC is based on magnetic-inductive technology and on the relation between magnetic and mechanical material properties.

This non-destructive approach eliminates the need for destructive tensile testing and provides reliable quality data on the complete strip length and strip width directly during the production process.

In addition, non-destructive tensile testing is often more cost-effective, as the process does not have to be interrupted to take material samples for each test. The results are available immediately at each step of the process so that material can be released without delay.

More Solutions

In the production of steel and aluminium strips, the increased demands on new materials and ever more complex components require an increasingly higher level of process reliability. With our innovative quality assurance systems for the cold rolling area, you can optimise your processes - and thus also your product quality.

All EMG systems are based on the same hardware and software structure. Benefit from the use of our broad solution portfolio and reduce your TCO (Total Cost of Ownership).  


EMG SORM® is the online measuring system for recording roughness parameters on running strips. Roughness characteristics are an important quality feature of uncoated and surface-finished strips.



EMG eMASS® is a turnkey system for stabilizing fast running ferromagnetic steel strips based on electromagnets.



In hot-dip galvanizing lines, the thickness of the zinc layer on the metal strip is adjusted with the aid of compressed air-driven blow-off nozzles - so-called air knives - directly above the zinc pot.


EMG BREIMO - Strip width measurement

EMG BREIMO is the non-contact, optical strip width measurement of steel strips in a continuously running process.


EMG SOLID® - Oil layer measurement

Increased demands on new materials and ever more complex components increasingly require higher process reliability.
