M1 AIR is a pneumatic bore gauge particularly suitable to test components with very tight tolerances (IT2 to IT7) and roughness Ra < 0.8 mm.
The measurement principle is based on the variation of pressure, which is proportional to the distance between bore gauge nozzles and part under test.
The measurement is obtained by means of the so-called "balanced pneumatic bridge" system, with differential pressure transducers and electronic amplification of the signal. The signal is converted from analog to digital through electronic converters.
Three retooling ranges are available:
- 3-4.15 mm (measuring range max 0.03 mm)
- 4.15-6.3 mm (measuring range max 0.05 mm)
- 6.3-100 mm (measuring range max 0.1 mm).
