Air spring height measurement arrangement

摘要

The subject invention relates to an air spring height measurement arrangement comprising a magnetic field transmitting arrangement (110) and a magnetic field receiving arrangement (120). The magnetic field transmitting arrangement is adapted to adopt a first state and a second state with regard to the magnetic field receiving arrangement. One of the magnetic field transmitting arrangement (110) and the magnetic field receiving arrangement (120) comprises a first coil (141) and a second coil and the other comprises a third coil (143). A first central axis (161) of the first coil and a second central axis (162) of the second coil enclose a first angle (171) and, in the first state, a third central axis (163) of the third coil (143) and the first central axis enclose a second angle (172), which first and second angle cannot be 0°.
