In a device for measuring the contact pressure of current collectors, a microbending modulator, known per se, is used as pressure sensor (1) which is installed in an optical waveguide path (9, 10). This modulator is constructed in the form of a mechanical structural element existing at the current collector, particularly in the form of a mounting element (12) used for connecting the collecting strip (14) with the pallet and is installed in its place as exchange element in the current collector. <IMAGE> |
