µ-Sen an independent and high-performance partner within the wind energy branch

µ-Sen is an independent and high-performance partner within the wind energy branch. The company located in Rudolstadt (County Thuringia) owns its competence at the field of body sound measurements. This technology is being used by µ-Sen company for the proactive equipment health monitoring (Condition Monitoring) of the power drive train of wind power units.

The Condition Monitoring System Omega-Guard® is the key product of µ-Sen in wind energy sector. Since the beginning of 2001 Omega-Guard® was tested in numerous wind power units of different types by various manufacturers. The successful diagnose regarding different damages of the wind power unit drive trains underlines the suitability of this systems for use in early fault detection. Therewith, Omega-Guard® serves for avoiding unanticipated damages as well as machine downtimes and potential high costs being caused by consequential damages (drive shafts, generators, bearings respectively wind power unit drives) resulting there from.

The realization of approved and latest diagnostic algorithms as well as their implementation into a modern fail-safe industrial hardware conception has formed the base for the approval by AZT (Alliance Centre for Technology).

(Novelty) The distinctive sensor technology know-how of µ-Sen yielded to the development of µ-Bridge. µ-Bridge is a body sound sensor which in comparison to conventional acceleration sensors operates in the low-frequency range. Therefore, it can be used in an outstanding manner for direct diagnosis of low rotating drive train components (for example planetary stage of the wind power gear unit and main bearing).
Omega-Guard® with its modular hardware conception and its open data structure offers manifold extensibilities and integration opportunities.
With this context there should be pointed out following opportunities:
- (Novelty) Wing Monitoring and – diagnosis (co-operation with IGUS GmbH)
- Structure Monitoring (tower, lattice tower)
- (Novelty) Incorporating maintenance by permanent lubricating (co-operation with perma-tec GmbH)

(Novelty, important for the technically skilled operating staff (works-manager), completes the previously exclusive diagnostic function of the system ) Further monitoring tasks having specific importance for the technical operation mode (for example parameter coupling of various temperatures and operational pressures) can be freely defined by the System Omega-Guard® , including automated notification. Data transmission can be realized optionally by SMS, email and Internet communication.

(Novelty) Furthermore the open data conception enables the simple connection to already existing database conceptions. Thus, the integration into an equipment operating software independent from the manufacturer of the wind turbine can be realized.

The performance manifoldness of µ-Sen GmbH will be accomplished and supplemented by various service activities. Besides of training and instructions for customer staff on site the delivery of independent certificates and expert opinions is included as well.

Since July 2003 µ-Sen offers a mobile diagnostic equipment to experienced users, too.

All prospective buyers and visitors will be invited for discussions with µ-Sen at the International Trade Fair WindEnergy 2004 ( May 11-14, 2004, Hamburg).
You will find us at the stand 434 in exhibition hall 7 EG.

Furthermore, we would like to invite all interested customers and visitors to participate in our workshop themed “Profit with wind II“ being held on June 17, 2004. The contents of this workshop should highlight the way from Condition Monitoring System towards an Integrated Maintenance Conception. The agenda as well as venue will be announced presently on our Website www.my-sen.de.
