摘要： A method is disclosed for operating a sensor arrangement having at least one measuring sensor and at least one reference sensor for recording the same physical variable, and having an analysis unit electrically connected thereto, with a characteristic of the sensor arrangement being recorded in an initialization phase from measured values of the at least one measuring sensor and of the at least one reference sensor, and an alarm being given during continuous operation if the deviation from the characteristic lies outside a tolerance band. It is proposed to suspend the alarm dynamically so long as the changes in the measured value in the variation over time of the at least one measuring sensor or in the variation over time of the at least one reference sensor differ by more than a definable limit within a definable time interval.

摘要： A protective circuit arrangement is disclosed for electrical equipment supplied, for example, from a conductor loop in surroundings subject to explosion hazards in process engineering installations. To suppress current flow from an energy store of the electrical equipment into the conductor loop, an exemplary cascadeable switchgear cell is disclosed, having a first transistor, which allows the loop current to pass, and a second transistor, which short-circuits a parasitic base-emitter diode of the first transistor.

摘要： A method is disclosed for determining a characteristic of a sensor arrangement having at least one measuring sensor and at least one reference sensor for recording the same physical variable, and having an analysis unit electrically connected thereto. The characteristic is determined from measured values of the at least one measuring sensor and of the at least one reference sensor. It is proposed to record a characteristic point during continuous measurement operation, starting with the first time the sensor arrangement is put into operation, when a definable measurement point is reached in a process for the first time, if the changes in measured value in the variation over time of the at least one measuring sensor and in the variation over time of the at least one reference sensor remain within a definable tolerance band within a definable time interval.
