The new MESSKO® MSense® x2.5 oil analysis sensorOil analysis at its best – accurate results and constant functionality from MESSKO

Oil analysis sensors have one job to do: they make a measurable contribution to extending the

service life of cost-intensive oil- and paper-insulated transformers. To do this they require two quali-

ties: robust technology for continuous functional safety and intelligent measurement procedures for

reliable values – both of which the new MESSKO® MSense® x2.5 provides.

Intelligent measurement procedure ensures reliable valuesExperts all agree that hydrogen, carbon monoxide, and moisture in the insulating oil of power trans-

formers are the primary early indicators of possible damage in the transformer with thermal or elec-

trical causes. The MESSKO® MSense® x2.5 focuses on these early indicators and continuously

monitors their concentrations.

The 2-stage measurement procedure used ensures that the results are free from distorting environ-

mental influences. The measurement chamber is flushed with ambient air before each measure-

ment to produce a correct blank value as a starting point for the measurement. Interfering influ-

ences are detected and taken into account in the subsequent gas measurement. The gas-in-oil

analysis can therefore be based on an accurately determined, non-distorted measurement basis

and provides highly accurate results.

Solid housing with robust stainless steel pipeThe solid housing protects the oil analysis sensor from extreme environmental influences. No mat-

ter whether used in the Arctic, desert or rainforest, the MESSKO® MSense® x2.5 is perfectly

equipped for all climatic conditions. The robust stainless steel pipe provides optimum all-round

protection to the sensitive gas extraction and measurement unit. What's more, it's not affected by

aggressive ambient conditions and makes possible measurement directly in the transformer's oil

flow.

On request, the oil analysis sensor can be supplied with integrated display for reading the mea-

surements and parameterization directly on the device.

Suitable for all applicationsThe MESSKO® MSense® x2.5 can be integrated directly in the transformer's oil flow via an inlet or

retrofitted in an oil loop using a bypass, making installation easy and reliable under all conditions.

Alongside the varied installation options, Messko offers its customers extensive oil analyses in the

analysis lab and rapid on-site service provided by a worldwide network.

MESSKO® MSeT® softwareThe intuitive MESSKO® MSeT® parameterization software can be used to define the limit values

and the number of measurements per day – not necessarily those set in the factory. Lastly, the

software's functions include a comprehensive rights and roles concept.

All hydrogen, carbon monoxide, and moisture concentration measurements can be traced back 4

years using an internal memory. They can be read and saved via a USB port and transferred to

MESSKO for further analysis.
