Abstract
The pulse tachometer for measuring the rotation of a rotating element (A) is characterized in that it comprises an inductive proximity sensor (10) placed in the vicinity of this element (A) in order to generate an electric pulse (100) upon each revolution of the element (A), a sender (20) connected to this sensor (10) for receive this electric pulse (100), shaping it and converting it into an optical signal, an optical-fibre link (30) connected to this sender (20) and to a receiver (40) for receiving this optical signal from the sender (20) and routing it to this receiver (40) in order to use it so as to calculate the speed of the rotating element. Application to rotating machines, for example turbine generators.
