OUR COMPANY PROFILE

Magnetic Products and Services, Inc. is the leader in pro-viding services and specialized equipment for shaft currentcontrol, magnetic field measurement, and for the removalof residual magnetism.

Owner, Marilyn Nippes has been CFO since MPS incorporatedin 1980. Founder Paul I. Nippes, P.E., is a pioneer in solving shaft current problems and designing correctivesolutions. A Fellow of IEEE, Paul served as a Chairman ofANSI C50, and IEC SC2G for many years. He holds aB.S.E.E. from Penn State University (1950) and a M.S.E.E.from the University of Wisconsin (1955). In 2004 he washonored as the first recipient of the Cyril B. Venoit, EnergyConservation Award from IEEE. For over 40 years, Paul hasserved the industry as a highly respected consultant.

SHAFT CONDITION MONITORING TECHNOLOGY

WITH MPS VCMs

Whether you have a turbine, compressor, motor, or generator, VCM technology “listens” for subtlewarning signs in the machine‘s most informative sensor, the rotor.

By heeding the warnings, you can reduce machinedowntime and improve performance. You can also prevent expensive damage to bearings, seals and other components. VCM output signals and alarmsmay indicate problems that are due to:

Loss of shaft groundingStatic electricityResidual magnetismShaft or rotor rubs

In electrical machinery, the VCM also indicates:

Shorting of bearing insulationLow-level stator winding faultsTurn shorts in the windingsUneven air gapsAnd more...

ARE YOU SAFEGUARDING YOUR ROTATING MACHINERY?

Do you have advance warningof problems?

Are you successful in schedulingshutdowns?

Is your machinery operating at top efficiency?

Is the residual magnetism in your machinery at safe levels?

MPS Offers Solutions…

MPS specializes in the evaluation and determi-nation of root causes of stray shaft current and

voltage damage in anyrotating machinery. MPS GaussbusterEngineers perform ShaftVoltage Surveys World-wide to measure shaftvoltages and groundingcurrents to determineyour machine’s damag-ing power potential andrecommends optimum

shaft grounding and monitoring systems foreffective problem resolution.

Explosion-Proof CertifiedMPS VCMs can connect to any insulated brushand condenses valuable shaft current and voltage infor-mation in the signal-conditioning circuitry for immediate retrieval, utilization and response or remote evaluation.

VCMs are available in explosion-proof and non-explosion-proof enclosures and also offeredare configuration options for Rack Mount and Hand-Held VCM Monitoring Solutions.

The MPS VCM-C displays grounding current andungrounded shaft voltage measurements. Designed for use by operators where continuous monitoring is not needed. Easy to install. Battery Powered.

The MPS VCM-E continuously monitors groundingbrush currents and shaft voltages. For use on large and critical machinery. Provides a local display andcontinuous 4-20 mA signals out to tracking device or control room computers. Receptacle Powered.

MPS Gaussbuster Engineers can also assistin the selection and placement of shaft groundingbrushes on all types of units as well advise with the integration into plant DCS or Data Acquisition system.
