The pneumatic measuring device comprises in particular a pneumatic circuit having a first branch 15 provided with an inlet nozzle 16 and with measuring nozzles 17, and a second branch 19 provided with an inlet nozzle 20 and with a reference nozzle 21. A differential pressure transducer 22, of the type containing a semiconducting element, enables the pressure difference between the branches 15 and 19, and a signal to be sent, by the terminal 23, representing the dimension measured outside the nozzles 17. The complete pneumatic circuit, with the pressure transducer, is contained within the measuring pin 12. <IMAGE>
