Portable Balancing Machine-Field Balancers

Jp Balancing Company’s range of portable field balancer and analysis, balancing and predictive maintenance has been enhanced with the new DM-3 instrument.

 

Equipped with an ample, backlit, high resolution LCD colour screen, DM-3 can be used in all types of lighting conditions.

 

Ease of use, calculation power and intuitive methods for the setting/presentation of measurements and graphs are the main features of this instrument.

 

The analysis functions provide the information needed for machine diagnosis and diagnosis of the condition of the bearings so the most appropriate maintenance work can be identified.

 

The balancing function can be used to balance any type of rotating body on one or more plane irrespective of size and weight.

 

The vibration trend over time, spectral analysis and Bode plot, which are essential tools for defining the corrective action needed with extreme precision, are all visible directly on the screen.

 

All of the readings taken can be saved in a database using sophisticated software for effective and rational organisation of predictive maintenance.

 

The equipment is supplied with standard accessories (2 accelerometers with a heavy-duty spiral cable, Hi-Speed 250,000 cpm photocell, USB stick, angle rule) sufficient for performing all of the main functions. Various optional accessories are also available (other types of sensors, extensions, Bluetooth printer) for when the equipment needs to be used in special conditions.

 

The software package, which can be installed on a PC, can perform data acquisition route creation (Route Manager) functions and provides diagnostics tools (Advanced Diagnostic Software).Three different levels are available to meet all requirements: storage, detailed analysis, diagnostics, measurement comparisons, trends, spectrums, orbits.
