Method for monitoring several sensors each emitting a signal representing a parameter comprises determining a time point with compared state to which the parameters have the same value plus a tolerance region and comparing the parameter and releasing an error when the parameters deviate by a value larger than a maximum deviation. An independent claim is also included for a sensor arrangement of several sensors each emitting a signal representing a parameter. Preferred Features: At least two sensors representing the same physical parameter form a path and are tested to determine whether the parameters have the same value plus a tolerance region. Verfahren zur Überwachung mehrerer Sensoren, die jeweils ein eine Messgröße repräsentierendes Signal abgeben, wobei die Messgrößen jeweils mindestens zweier Sensoren die gleiche physikalische Größe repräsentieren, umfassend die Schritte: DOLLAR A - Ermitteln eines Zeitpunktes mit ausgeglichenem Zustand, zu dem die den einzelnen Sensoren zugeordneten Messgrößen den gleichen Wert zuzüglich eines Toleranzbereiches haben; DOLLAR A - Vergleich der durch die Signale der Sensoren repräsentierten physikalischen Größe und Ausgabe eines Fehlers, wenn die durch die Signale der Sensoren repräsentierten Messgrößen um einen Wert größer einer Maximalabweichung voneinander abweichen.
