The NO-VAR (NO-VARiation) technology developed for the Aeroel Laser Micrometers allows one to simply get perfect diameter measurements, even in non thermally controlled environments, when the ambient temperature is significantly different from the reference temperature (20°C).

Thanks to this new technology it is possible to get in the workshop or in line, the same results that one would get in a controlled temperature metrology room when measuring any material and even when the ambient temperature is changing by some degree/hour.

You will no longer have to be concerned about frequent gauge remastering operations when the room temperature is changing, nor will you have to take into account part expansion.

The Aeroel Laser Micrometers are used by CERN – European Organization for Nuclear Research inside the LHC (Large Hadron Collider) experiment started in Genève (CH).

The Aeroel sensors are used to check the alignment of the collimators and the magnets at section 7 of the LHC and they are mounted on a wagon of the inspection train that runs along a monorail inside the 27 Km of the LHC tunnel. The wagon uses some digital cameras to get the position and the alignment of the collimators/magnets with reference to the wagon itself. The Aeroel Intelligent Laser Micrometers are used to measure the real time position of the wagon referred to the LHC tunnel, by checking the offset of a reference wire installed along the tunnel. The collimators are needed to avoid “losses” in the particle beam and they are installed in the most radioactive area of the tunnel: this is the reason for using a robot system to perform the alignment check.
