A sensor system for determining physical variables of a switchgear assembly having a sensor connection, which is designed for connection to the switchgear assembly, within which a humidity sensor and/or a pressure sensor and a light sensor for detecting light flashes are arranged. A switchgear assembly is provided that is filled, in particular, with a protective gas, comprising at least one such sensor system.

Sensor system for switchgear assemblies

A monitoring device is provided having a temperature-compensated pressure-measuring system, in which an electrical notification is output to the outside with use of a plurality of settable threshold values. Also, a high-performance switching system is provided that includes at least one monitoring device.

Temperature-compensated pressure gauge with a switch output

A measuring device according to the invention for determining the fill quantity of SFgas in an insulating chamber comprises a pressure transducer, a temperature measuring element and a processing device for determining the fill quantity of the SFgas from the pressure measurement value and the pertinent temperature measurement value, wherein the measuring device seals a corresponding opening of the insulating chamber and the SFgas to be measured acts directly upon both the pressure transducer and the temperature measuring element.
