ABSTRACT:
The invention discloses a method and an apparatus for explosion protection of plants, pipelines and the like by monitoring chronologically successive values of the system pressure in the potentially explosive area and by comparing these values with a predetermined pressure threshold, where the exceeding of this pressure threshold is used as a triggering criterion for initiating explosion protection provisions. According to the invention, instead of predetermining a constant value as the pressure threshold, the pressure threshold is updated continuously in accordance with the system pressure prevailing at that time. As a result, the pressure threshold can be set with a smaller safety margin above the system pressure than before. Brightness and temperature thresholds may also be used singly, or together with pressure in any combination in continuous value monitoring.
