Air-to-Electronic Converter


The Air Electronic Converter is a high definition air measure system.

It supplies dimensional and geometrical measures using pneumatic technology.

  • Ideal to measure small holes
  • Ideal for to measure dimensions with small tolerances (<10µm); resolution is extremely high (0.01µm)
  • Dimensional and geometrical measures performed without touching the part
  • Pneumatic measure devices offer simplification of production and low costs
  • Easy maintenance: short time to restart the machine tool
  • Flexibility and easy regulation
  • Can be connected to all pneumatic measuring devices (Marposs and third-party)

Marposs Air Electronic Converter is  characterized by a high flexibility of use, making it perfectly adaptable to the most different customer application needs.

  • Zero regulation through regulator on the front panel
  • Pneumatic sensitivity  through regulator on the front panel

The flexibility allows it to be connected to any pneumatic measure device typologies, which are characterized by a wide variety of air nozzle and gap distance from nozzle and part to be inspected

  • Pneumatic air plug
  • Pneumatic air ring
  • Pneumatic air plug and ring for taper HSK e ISO
  • Pneumatic snap
  • Manual and automatic measuring bench 

The Marposs Air Electronic Converter can be supplied as a single or modular assembly, from 2 to 6 units.

It is engeneered to be used on all workshop environments.  It is perfect for the inspection on mechanical grinding post and in-process.

Each Air Electronic Converter is able to handle one air measure channel.
