BRAKE SIGNAL TRANSMITTER FOR AN ELECTROPNEUMATIC AND/OR ELECTROMECHANICAL BRAKE SYSTEM

A brake signal transmitter (), for an electropneumatic and/or electromechanical brake system () of a vehicle (), includes a movably arranged plunger piston (), a first displacement sensor (), and a second displacement sensor (), which is redundant in relation to the first displacement sensor (), for detecting a movement () of the plunger piston (). A signal transducer device () having two redundant signal transducers () reads out the detected movement (). The brake signal transmitter () has a pressure space () and a sensor device () for sensing a measurement variable () relating to the pressure space (), and the movement () of the plunger piston () can be determined by sensing of the measurement variable ().
