The measurement principle is based on pressure change readings, which are proportional to the distance change between the measuring instrument nozzle and the part.

Measurement can be carried out through balanced air bridge technology using differential pressure sensors and electronic signal amplifiers.

Then the air/electronic converter directly converts the signal from analog to digital.

For tolerances of<6 μ m or>60 μ m, Marposs can design and provide specially customized gauges.

Measure components with strict tolerances

There is no risk of wear and tear on the parts

• Zero calibration is carried out by calibrating the ring gauge with standard components
• Measurement range: The maximum measurement range of measuring instruments with diameters ranging from 6.3 mm to 10 mm is 0.1 mm
• Suggested maximum roughness is 0.8 μ m Ra
• Repeatability (± 2 σ):< 0.5 μm
• Air source: Highly purified and filtered dry air (filtration rate<0.5 μ m)
• Gas supply hose: inner diameter 4 mm, maximum length 2 meters
• Average consumption:< 1000 l / h
