The invention relates to a compressor casing for an exhaust gas turbocharger, said casing being produced by an injection-molding method. The exhaust gas turbocharger has a turboshaft that is mechanically connected to a compressor wheel and a turbine wheel. The invention also relates to a method for producing said compressor casing. The aim of the invention is to allow an inexpensive, reliable and exact detection of the speed of the rotating parts (turbine wheel, compressor wheel, turboshaft) of an exhaust gas turbocharger. For this purpose, a sensor for measuring the speed of the turboshaft is embedded into the compressor casing during injection molding, thereby creating a sensor that is configured as a component that is integrated into the compressor casing itself. |
