Dimensional Inspection Systems Based on Air Gauges

In the paper, the short overview of the air gaging have been presented. The most common methods of the back-pressure measurement have been described. The problem of the pneumatic-electric conversion of the measurement signal has been pointed out. The system based on the air gauges integrated with piezoresistive pressure transducers have been presented. In those systems the results of measurement are achieved in digital form, they are processed and recorded. The appropriate software enables the analysis of parameters of the process, too. Some of the characteristics of the Pneutronik device have been investigated and presented.
