The subject invention relates to an air spring height sensor comprising a transmitter unit (102) for transmitting a height measuring signal, a receiver unit (101) for sensing a height signal, a carrier frequency switching unit (103), and an evaluation unit (200). The receiver unit and the transmitter unit are adapted for being mounted to opposing mounting elements (10, 20) of an air spring (1). The transmitter unit is switchable between different carrier frequencies (121, 122) of a height measuring signal. The evaluation unit comprises a frequency filter (213) being switchable between different carrier frequencies, wherein the carrier frequency switching unit is adapted for switching the carrier frequency of the frequency filter at a predetermined first point of time and the corresponding carrier frequency of the transmitter unit at a predetermined second point of time, wherein the first point of time is prior to the second point of time.
