    摘要： The invention relates to a speed sensor (100) for detecting a speed of a magnetizable object. The speed sensor (100) can be supplied with an electric alternating signal with a first frequency by an electric signal source, said speed sensor comprising: a primary coil (101) for generating a magnetic alternating field with the first frequency; a first secondary coil (103) and a second secondary coil (105), wherein the first secondary coil (103) and the second secondary coil (105) can each be magnetically coupled to the primary coil (101) via a magnetizable object, and a first electric signal can be induced in the first secondary coil (103) and a second electric signal can be induced in the second secondary coil (105) by the generated magnetic alternating field; a Goertzel filter bank (107) for detecting a first amplitude value of a spectral component of the induced first electric signal and a second amplitude value of a spectral component of the induced second electric signal in the event of a second frequency which differs from the first frequency; and a processor (109) for determining the speed of the magnetizable object depending on the detected first amplitude value and the detected second amplitude value. The second frequency is preferably double the frequency of the excitation frequency. The rotational speed can be ascertained from the difference between the detected amplitude values, the relationship being definable using calibration data.
