are displayed on a green-yellow-red condition scale. This enables you to
quickly investigate the cause of a reading in the red or yellow zone.

Technical solutions for a variety of operating conditions
The backbone of all predictive maintenance is up-to-date data on machine status,
obtained with two well-tested frontline techniques to identify problem areas. Shock-pulse
monitoring provides early detection of bearing damage and marginal lubrication conditions. Overall vibration severity monitoring, according to ISO standards, detects common
mechanical faults such as imbalance, misalignment and loose parts.
Vibration severity
The machine evaluator measures overall vibration velocity, acceleration and
displacement according to ISO 10816 standards, with menu selection of all specified
machine classes and their alarm limits on a green-yellow-red scale. Historical trends
are available both on the instrument and in the software.
Vibration analysis
With vibration analysis, you can diagnose machine problems such as imbalance,
misalignment, and bearing and gear damage. The vibration time waveform is
recorded and summarized by nine statistical parameters, including crest factor,
kurtosis and skewness. FFT analysis produces a 12,800-line spectrum up to 40,000 Hz
with true zoom and enveloping.
The resulting FFT spectrum can be overlaid with machine-specific fault frequencies
both in the instrument and the software.
Shock-pulse analysis for bearing evaluation
The shock-pulse method is a reliable and proven technique for monitoring ball- and
roller-type bearings. It provides accurate information on the mechanical health and
CONDITION MONITORING SOLUTIONS > CONDITION MONITORING SOLUTIONS > CONDITION MONITORING SOLUTIONS > CONDITION MONIT
lubrication condition within the bearing. The measurement results are displayed
numerically and on a green-yellow-red scale for immediate evaluation of the bearing
and lubrication condition.
Shock-pulse spectrum
Shock-pulse spectrum is a high-frequency technique for performing a detailed
analysis of the bearing condition. A time record of the signal from a shock pulse
transducer is subjected to an FFT analysis. This provides a spectrum that is compared
with the rotational frequencies of the bearing components. In addition, it can analyze
other periodic shock sources, such as gear damage.
Orbit analysis
For all machines with journal bearings, simultaneous measurement with two vibration
transducers supplies an accurate graph of the shaft center line movement.
Structural resonances
Run up/Coast down measurement and bump test are tools for root cause analysis.
They show the machine frame vibration characteristics, resonance frequencies and
the reaction at critical speeds.
RFID tags
As labor-saving devices, RF identification tags can store measurement point data and
the latest measurement results. The machine evaluator is programmed by reading
tags via radio transponders.

A poorly aligned or out-of-balance machine wastes energy and causes premature failure. The machine evaluator is a
state-of-the-art maintenance tool for fast and easy alignment and balancing.
Laser shaft alignment
Machine evaluator uses a special line
laser technique for the alignment of
both horizontal and vertical machines.
The LineLazer™ kit contains detector
units and fixtures.
For easy and accurate targeting, the
detector units send horizontally spread
laser beams against large vertical
receptors. Only one connecting cable
to the instrument is needed. The laser
beam is coded to guard against
interference from other light sources.
Automatic precision inclinometers
constantly measure the angular shaft
position. Three measurements over a
shaft rotation angle well below 180
degrees determine present alignment.
The graphical interface guides the user
through the alignment process.
Dynamic balancing
With the machine evaluator, single- and dual-plane rotor balancing in accordance
with modern standard methods are easy operations. One can apply the traditional
four-run technique or the two-run method with time synchronous measurement
triggered by a tachometer connected to the instrument.
The machine evaluator supporting functions make it easy and reliable to conduct
field balancing. It saves an influence matrix, which allows fast re-balancing
calculations without stopping the machine to attach a test weight.
An initial vibration measurement with spectrum analysis clearly show the
existence and extent of imbalance, and thus the need and probable success of a
balancing operation.
The machine evaluator calculates the suitable trial weight and suggests a number
of alternatives for correcting the imbalance.
Correction mass, with the trial weight removed or remaining in place, can be
radially displaced and split between two of the rotor partitions. For weight
removal, drill hole diameter and depth for various materials are given.
Weight position is displayed as the angle or distance measured along the rotor
circumference. All trial weights on the rotor can be replaced by one final weight.
For all methods, a final run can be made to check the balancing results and, if
needed, a data file can be saved for future references.

Condmaster®Nova Software
(supplied with ME-I and ME-II)
Condmaster®Nova
Condmaster®Nova software platform is designed to
be used in conjunction with the machine evaluator
to provide an efficient condition monitoring solution.
With Condmaster®Nova software you can obtain
practical solutions for condition diagnosis suited to
your environment and applications.
Your primary tool for fast fault detection is the
graphical overview, which identifies potential
trouble spots.
The software accepts data from most Timken
handheld and online condition monitoring systems.
The software’s modular design allows it to be fitted
to your selected hardware. It supports preventive
maintenance activities, such as time planning, trend
graphics, statistics and reports. The system
interacts with other maintenance software. Alarms
via email and text messages can

be configured.
Condmaster®Nova contains an extensive bearing
catalog and evaluation models for shock pulse,
vibration and lubrication condition. Preprogrammed fault frequencies assist in pinpointing
machine fault signatures in spectrum graphs.
Alarm lists are generated on the basis of
automatically applied evaluation rules that can be
modified by customer-defined thresholds.
Green-yellow-red coding at every surveillance level,
from plant to individual measuring point, supplies a
fast overview of all monitored equipment.
The FFT Spectrum can be overlayed with machinespecific vibration fault frequencies.

Condition monitoring requires an investment in personnel, instrumentation and
training. You can start with a standard machine evaluator set and add functionality
as your needs and experience grow.
Machine Evaluator I Set
The ME-I set consists of a data-logging instrument to measure speed, temperature,
shock pulse and overall RMS vibration. It communicates with Condmaster®Nova
software and also accepts manual data input. Individual functions may be added to
the instrument to best meet your particular requirements. You can buy upgrade
functions with the initial purchase or in the future in the form of an update file.
Purchasing upgrades in the future would allow you to expand slowly as you gain
experience and grow your reliability program.
Machine Evaluator II Set
The ME-II set has all the same features as the ME-I with the addition of advanced
vibration analysis functions that include time wave form, FFT spectrum and fault
symptom analysis.
