An improved device for measuring the contact force between a contact wire and a power collector in an electrically powered vehicle, specially an electrical railway vehicle, by use of optical fiber force sensors. To this end, two compact force sensors are arranged between the base body (7) of the contact strip (6) and the pantograph rocker frame (5) or between the wearing element or shoe (8) and the base body (7) of the contact strip (6). Each sensor includes a deformable body (11), which is elastic in an axial direction but highly rigid crosswise, with the body being fitted with an integrated optical fuber reflex sensor (19). Axial deformations of the deformable body (11) equivalent to the contact force are detected by the reflex sensor (19) with high resolution, accuracy and no interference, are then signaled to a device (27) via optical fibers requiring no potential and converted therein into contact force-equivalent signals (28) or instructions (29).
A device for measuring the contact force between a contact wire and a pantograph of an electrically-powered vehicle, particularly an electrical railway vehicle, said device having at least one fiber-optic sensor for ascertaining a contact force between the contact wire and the contact strip of the pantograph and a device for sensor control and sensor-signal processing that is connected to the at least one sensor for separate-potential signal transmission;
