Abstract
A sensor for measuring the rotational speed of a turboshaft of a turbocharger includes a sensor housing and a sensor element which is positioned in the sensor housing and which senses a variation of a magnetic field caused by the rotation of the turboshaft. In order to provide a sensor for measuring the rotational speed of a turboshaft which can be produced simply and at low cost and also can be integrated in a turbocharger without major structural modifications, the sensor element can be positioned outside the turbocharger, on or in a compressor housing, and a pole piece is arranged on the sensor element in such a way that it concentrates the magnetic field in the sensor element.
