For non-contact monitoring of external and internal sizes of products of a wide range of vacuum ceramics, including with a metallized surface.

Working of system is based on the principle of aggregation of various optical-electronic methods of measuring the sizes: shadow, structural lighting, television.

1. Noncontact measurements
2. Quick response due to application of the modern element base
3. Friendly user interface

- measuring unit
- computer
- operator desk
- uninterruptible power supply
- the system saves information on all products in the MS Access database

Various ring products control with the parameters mentioned above produced by electronic,
mechanical engineering and other branches of industry.

The system is under testing at «NEVZ-Soyuz ( Novosibirsk city).
