A valve drive mechanism is designed as a piezoelectric actuator. At a preset time, a valve element (VE) moves into a valve seating (VS) from a position away from a VS. A signal characterizes a piezoelectric voltage (VINJ) and its branching-off is determine...

The method involves converting a measurement signal acquired in analog form and representing the electrical operating state and/or operating process of an electrical line (7,9) and/or the final control element (3,5) into a digital measurement signal and us...
