摘要

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.
