Abstract
An air spring height sensor (100) is provided which comprises a receiver (101) for receiving a height signal and an evaluation unit (200). The receiver is adapted for being mounted to an air spring so as to sense a height signal with respect to said air spring. The evaluation unit comprises an input terminal (201), a multiplexer (240), a first signal branch (210) starting from the input terminal and terminating at a first multiplexer input (241), and a second signal branch (220) starting from the input terminal and terminating at a second multiplexer input (242). The first signal branch includes a first amplitude limiter (211) being adapted to cut off the amplitude above a predetermined first threshold value. The multiplexer is adapted to select a measurement signal from one of the inputs of the multiplexer.
