New portable field balancer and vibration analyser

Schenck Balancing and Diagnostic Systems, recognised as a world leader in balancing technology, announces its re-entry into field balancing and vibration analysis with the SmartBalancer

Schenck Balancing and Diagnostic Systems, recognised as a world leader in balancing technology, has announced its re-entry into field balancing and vibration analysis with the SmartBalancer.

The new Schenck SmartBalancer is the ideal tool checking the vibration of an assembly and for accurately identifying and correcting unbalance in rotating machinery.

With the SmartBalancer, operators have complete on-site field balancing capability and the compact, battery powered instrument enables rotors to be balanced quickly, accurately and cost effectively without dismantling the machine.

Rotors of almost any size or weight can be balanced in one or two planes - statically and dynamically.

With its ease of operation, universal application and field proven accessories, the SmartBalancer makes field balancing fast and easy - even for less experienced staff.

Operators are prompted through the sequence of steps required to measure and eliminate rotor unbalance, using up to four measurement points to reduce error, provide complete versatility and superior accuracy.

A variety of combinations are possible such as simultaneous horizontal, vertical and axial measurements, or two horizontal and two vertical measurements.

"Vibration is an excellent indicator of the status of individual machine components and of the machine as a whole," says Nigel Best, manager of Schenck Balancing and Diagnostic Systems (UK).

"The new SmartBalancer performs a broadband measurement of absolute bearing vibrations to compare measured values with specified limits to ascertain whether a machine is operating within its specified vibration level, or if this is exceeded whether field balancing is necessary".

To determine the causes of vibration, the SmartBalancer also offers FFT (Fast Fourier Transform) analysis with constant absolute bandwidth and SmartFFT with constant relative bandwidth.

Both methods enable measured vibrations to be separated into harmonic portions and displayed with frequency and amplitude in the form of spectral lines.

Results can be viewed numerically or in polar display to provide an easy to read graphical representation.

Correction locations can be identified in polar or component form based on the configuration of the rotor that is being balanced.

Rotors that have limited correction locations, such as a fan for example, can be easily balanced with the component correction feature.

Users are free to define the available correction locations on the rotor whether they are equally or unequally spaced.

All balancing results can be recorded in the SmartBalancer along with a description of the machine, sensor position, date and time.

Measurement data can also be downloaded to a PC or laptop for filing and further analysis using the Schenck SmartReport PC software supplied with the balancer.

Users can create expert balancing reports with Bode and Nyquist plots and cascade/waterfall charts.

Measurement results can also then be imported to other programs in the Windows Office suite such as Word or Excel for further processing.

As well as the highly specified technical features the Schenck SmartBalancer offers a unit at an extremely competitive price.

The unit, with no hidden extras, costs less than GBP7,000.
