摘要：The invention relates to a device for measuring the speed of rotation of a heatengine, in particular for motor vehicles, comprising: a measurement apparatus (13)capable of receiving a signal so as to indicate a value corresponding to the speed ofrotation of the said engine, a rotating electrical machine (11), mechanically coupled to theheat engine and capable of delivering at least one signal representative of the speed ofrotation of the said heat engine, the said signal having a characteristic depending on thetype of rotating electrical machine (11), and also a conversion means (12), insertedbetween the said rotating machine (11) and the said measurement apparatus (13),capable of delivering to the said measurement apparatus a signal (D11; M2; K3) having afirst number of pulses per turn, on the basis of one or more signals (A11, A12, A13; A2;A3) having a second number of pulses per turn and delivered by the said rotatingmachine (11).
