Abstract
A pneumatic measuring device is disclosed which comprises a pneumatic circuit containing a first branch (15) equipped with an inlet nozzle (16), oppositely disposed measuring nozzles (17) and a second branch (19) equipped with an inlet nozzle (20) and a reference nozzle (21). A differential pressure transducer (22) having a semiconductor element enables the difference in pressure between the branches (15) and (19) to be measured and to supply through a terminal (23) a signal representing the dimensions measured opposite the nozzles (17). The pneumatic circuit system, with the pressure transducer, is included in the measuring spindle (12).
