Introduction

Global presence localsolutions

With over 100 years of experience, SKF stands

alone as a total solution provider for maximizingmachine and plant productivity. With a

reputation for quality, technological innovation

and service that spans the globe, SKF brings

what no other vendor can to the maintenance

arena.

and worldwide distributors provide access to

the range of SKF bearings, maintenance

products, lubricants and condition monitoring

instrumentation and software, independent of

your location.

In any kind of rotating machinery, from hugerolling machines to the smallest of motors, the

bearing knows if there is a potential problem.

As the primary interface between moving parts,

the bearing is literally the diagnostic heart of

the machine.

Misalignment, unbalance, looseness and

friction, are all telegraphed through the

bearing. Understanding the information

coming from this diagnostic pulse and then

applying the latest and best technology to the

problem is the key to raising machine

productivity and lowering operating costs.

easily, quickly and accurately check the

condition of rotating equipment throughout

your facility. Equipping your maintenance

and operations personnel with this rugged,

ergonomic and easy-to-use instrument can

provide early warning of potential machine

problems before a costly failure occurs.

Multiple measurements with a single

device

The SKF Machine Condition Advisor provides

an overall Velocity vibration reading that

measures vibration signals from the

machine and automatically compares them

to pre-programmed International

Organization for Standardization (ISO)

guidelines. An Alert or Danger alarm

displays when measurements exceed those

guidelines. Simultaneously an Enveloped

Acceleration measurement is taken and

compared to established bearing vibration

guidelines to verify conformity or indicate

potential bearing damage.The SKF Machine Condition Advisor also

measures temperature using an infrared

sensor to indicate uncharacteristic heat.

Features

Quick and easy to set up and use,

measurements are shown on a bright

display viewable in low light to direct

sunlight. Free on-line training is also

available at SKF @ptitude Exchange.

Lightweight, compact and ergonomically

designed, the SKF Machine Condition

Advisor fits neatly at the belt line, in a

pocket or a tool kit. Exceptionally durable,

the unit is rated IP 54 for use in adverse

industrial environments.Alert and Danger prompts provide

increased diagnostic confidence.

Measuring Velocity, Enveloped

Acceleration and temperature

simultaneously saves time.

Efficient, economical and environmentally

friendly, the rechargeable SKF Machine

Condition Advisor operates 10 hours on a

single charge.

Flexible enough to work with standard

100 mV/g ICP accelerometers, an optional

external sensor can be used for hard-to-

reach locations.Features English, French, German,

Portuguese, Spanish and Swedish for

user convenience.

Understanding and using guidelines for

vibration

The SKF Machine Condition Advisor provides

a means to evaluate machine health based

on ISO 10816-3 and to evaluate the

bearings according to general guidelinesdeveloped from a statistical analysis of

existing databases.

How to choose the correct Alarm Velocity

Group for your machinery

The Alarm Velocity Group (G2&4or G1&3)

determines the instruments overall

vibration alarm limits. Therefore, select the

Group that best describes the general size,

type, and speed of the machinery being

measured. Note that these machine group

classifications are set forth in ISO 10816-3,which rates overall velocity vibration levels

for standardized machinery classifications.

Groups 2&4 (default)

ISO Group 2 and 4 classifications define the

following type of machinery:

Medium-sized machines and electrical

machines with a shaft height between

160 and 315 mm.

These machines are normally equipped

with rolling element bearings, but may

use sleeve bearings, and operate atspeeds above 600 RPM.

These machines include pumps with

multi-vane impellers and integrated

drivers.

Groups 1&3

ISO Group 1 and 3 classifications define the

following type of machinery:

Large machinery and electrical machines

with a shaft height greater than 315 mm.

These machines are generally equipped

with sleeve bearings, but may use rolling

element bearings.

These machines include pumps with multi-

vane impellers and integrated drivers.

Rigid or Flexible foundation?

An additional setting allows the specification

(when defining the overall alarm levels) of

measurements taken from machinery with

Rigid(default) or Flexiblefoundations.

Options are:

G2&4R (default)

Alert: 2.8 mm/s (0.16 ips)

Danger: 4.5 mm/s (0.25 ips)

G2&4F



G1&3R

Alert: 4.5 mm/s (0.25 ips)Danger: 7.1 mm/s (0.39 ips)

G1&3F




How to choose the correct Enveloped

Acceleration Classification for your

machinery

The Enveloped Acceleration Classification

(CL1, CL2,or CL3) you specify determines

the instruments bearing vibration alarmlevels. Therefore, the Enveloped Acceleration

Class that best describes the general size

and speed of the bearings being measured

should be selected.

Options are:

CL1

Bearings with a bearing bore diameter

between 200 and 500 mm and a shaft

speed below 500 RPM.

Alert: 1 gEDanger: 2 gE

CL2 (default)


between 200 and 300 mm and a shaft

speed between 500 and 1 800 RPM.

Introduction

There are many uses for this hand-held

non-contact, infrared thermometer. Rugged

and easy to use just aim, pull the trigger,

and read the temperature in less than a

second. Measures surface temperatures of

hot, hazardous, moving, or hard-to-reach

objects safely without contact.

The non-contact thermometer senses the

thermal energy radiated from an object with

an infrared detector. When pointed at anobject, the infrared detector collects energy

producing a signal that the microprocessor

translates as a reading on the backlit display.

As the trigger is squeezed, the object

temperature is continuously measured by

the infrared detector. This allows for fast and

accurate real-time readings.

This instrument features an extended

temperature range 60 to +1 000 C (76

to +1 832 F); dual laser sighting; bright

large amber back-light LCD display;

Maximum, Minimum, Difference (MAX-MIN)and Lock function for continuous

temperature scanning; programmable High

and Low audible alarms; selectable

temperature units (C or F); low battery

indicator and adjustable emissivity for more

accurate temperature measurements.

EmissivityEmissivity is a term used to describe the

energy-emitting characteristics of materials.

Most organic materials and painted or

oxidized surfaces have an emissivity of 0.95.

Inaccurate readings can result from

measuring shiny or polished metal surfaces.

To compensate for this, adjust the units

emissivity reading, or cover the surface to be

measured with masking tape or flat black

paint (< +148 C /+300 F). Allow time for

the tape or paint to reach the same

temperature as the material underneath it.Measure the temperature of the tape or

painted surface.

Introduction

The SKF Inspector 400 Ultrasonic Probesenses high frequency sounds produced by

operating equipment, leaks and electrical

discharges. It electronically translates these

signals by a heterodyning process, making

them audible, so that a user can hear these

sounds through a headset and see them as

intensity increments on a meter.

The SKF Inspector 400 Ultrasonic Probe

can complement your condition

monitoring program by providing you with

the following capabilities:

Pressure/vacuum leaks

As any gas (air, oxygen, nitrogen, etc.)

passes through a leak orifice, it generates a

turbulent flow with detectable high

frequency components. By scanning the

test area with the SKF Inspector 400

Ultrasonic Probe, a leak can be heard

through the headset as a rushing sound or

noted on the meter bar graph indicator. The

closer the instrument is to the leak, the

louder the rushing sound and the higher

the meter reading. Should ambient noise be

a problem, a rubber focusing probe may beused to narrow the instruments reception

field and to shield it from conflicting ultra

sounds.

Valve

Valve activity such as leakage or blockage

can be accurately checked while the valve is

on line. Properly seated valves are relatively

quiet while leaking valves produce a

turbulent flow as the fluid moves from the

high pressure side through the leak to the

low pressure side. Due to a wide sensitivity

SKF Inspector 400 Ultrasonic ProbeCMIN 400-K

and ultrasonic frequency, all

types of valves even in noisy

environments can be accurately tested.

Valve stems

Valve stems may be quickly tested for leaks

to atmosphere.

Steam trap inspection

Major steam trap manufacturers have

recommended ultra sound inspection of

steam traps as one of the most reliablemethods available. By converting theultrasonic elements of a working steam trap

into the audible range, the SKF Inspector

400 Ultrasonic Probe allows users to hear

through headphones and see on a meter

the exact condition of a steam trap while it

is on line. Blowby, machine gunning,

oversized traps or line blockage are all

easily detected.


markedly reduces confusion from

extraneous sounds or from heat transfer,

even when traps are extremely closetogether.

Electrical inspection

Arcing and corona discharge emit ultra

sounds at the site of emission. This

electrical discharge can be located quickly

by scanning the area with the SKF Inspector

400 Ultrasonic Probe. The signal is heard as

a frying or buzzing sound in the headset. As

Valve leakage. Pressure/vacuum leaks.

with pressure or vacuum leak detection, the

closer the instrument is to the discharge,

the more intense the signal.

Test switch gear, transformers, circuitbreakers, buss bars, relays, junction boxes,

insulators, and other electrical gear.

General mechanical inspection


can detect the early stage of a machines

mechanical malfunction. NASA research

has demonstrated that ultrasound

monitoring will locate potential bearing

10


11/40

Mechanical inspection.

Heat exchangers, boilers and condensers

In-leakage or pressure leakage can be

readily located with the SKF Inspector 400

Ultrasonic Probe. Fittings, valves, flanges

are all easily scanned for leakage. The high

frequency, short wave nature of ultrasoundallows operators to pinpoint the location of

a leak in high noise environments.

Condenser tubes and heat exchanger

tubes may be tested for leakage through

two (2) methods: Vacuum and Pressure.

Vacuum

The tube sheet is scanned for the telltale

rushing sound produced as the leak draws

air into the tube.

Pressure

Additional testing may be performed when

the system is off-line utilizing air pressure

around the tube bundle and scanning for

the rushing sound produced from the

leaking tube.

deficiencies before they are detected by the

traditional heat and vibration methods.

With the SKF Inspector 400 Ultrasonic

Probe, users hear the sound quality of a

bearing as well as monitor amplitude

changes on the meter. This complementsother monitoring instruments and adds to

the ability to trend, troubleshoot and

confirm potential bearing problems.

General mechanical inspection is easy with

the SKF Inspector 400 Ultrasonic Probe and

with very little training, users can learn to

test bearings within minutes. Current

vibration programs can achieve enhanced

diagnostic ability with the SKF Inspector

400 Ultrasonic Probe.

Prevent over-lubrication with the SKF

Inspector 400 Ultrasonic Probe by simplylubricating only until the meter reaches a

specified level. Over lubrication is one of the

more common causes of bearing failure.

General mechanical inspection of pumps,

motors, compressors, gears and gear

boxes: All types of operating equipment

may be inspected with the SKF Inspector

400 Ultrasonic Probe. Since the SKF

Inspector 400 Ultrasonic Probe works in a

high frequency, short wave environment,

problems such as cavitation in pumps,

compressor valve leakage or missing gear

teeth may be heard and isolated.Reciprocating compressor valve analysis

has also become successful with the SKF

Inspector 400 Ultrasonic Probe and

therefore many engine analyzer companies

now offer instruments with an ultrasonic

input port.

in the low to mid frequency range, and

indicates such structural problems asmisalignment, unbalance, mechanical

looseness and more. However, events

which occur in the higher frequency ranges

such as bearing and gear problems, can

also be detected by the SKF Machine

Condition Detector Pro IS with its

Acceleration Enveloping capability, a signal

processing technique which focuses on

enhancing the repetitious vibration signals

that characterize such problems.

Temperature

Temperature measurements enhance the

early warning benefit of the instrument by

offering a useful indication of mechanical

condition or the load applied to a specific

component, since, as a bearing or its

lubrication fails, friction causes its

temperature to rise.

The SKF Machine Condition Detector Pro IS

is certified Intrinsically Safe (IS) for Europe

and North America. The ruggedized SKF

Machine Condition Detector Pro IS is ideal

for use in the hazardous environments

typically found in the petrochemical

Industrial marketplace.

Go / No Go machine monitoring


is designed to provide a straightforward

approach to machinery monitoring. Theinstruments sensor affixes to a machine

point via a SKF MARLIN QuickConnect Stud

or magnetic bases for automatic collection

of vibration and temperature data. Green,

yellow and red LEDs provide easy-to-

interpret indications of machine status, so

operations or maintenance personnel can

quickly identify the need for more in-depth

analysis on a particular machine.

Multi-parameter monitoring capabilities


operates as a stand-alone device, or as anaccessory to the SKF MARLIN hand-held

mobile computers for Operator Driven

Reliability (ODR). When used with SKF

@ptitude Inspector companion software

and the SKF MARLIN QuickConnect line of

mechanical and computerized studs, the

complete system offers customers in non-

hazardous conditions the added power and

functionality of immediate in-the-field

feedback on alarm conditions, as well as

data storage, trending and analysis. Data is

logged for trending, Statistical ProcessControl (SPC) rule violation, and percent

change from last measurement and

baseline data.

SKF Operator Driven Reliability

(ODR) process ensures that operator

observations are accurately, thoroughly, andconsistently recorded and communicated.

Utilizing automated technology that is

linked to your maintenance strategy,

operators immediately respond to abnormal

process conditions, proactively, with in-the-

field corrective actions that help increase

production output. In the event of

degrading asset health, operators can

initiate work notifications to your

computerized maintenance management

system (CMMS), providing enhanced

awareness to maintenance management.

Vibration monitoring

When performing measurements, the SKF

Machine Condition Detector Pro ISs sensor

input signal is processed to produce two

vibration measurements for each

measurement POINT. Velocity vibration

General alarm capabilities

When used as a stand-alone tool, the SKF

Machine Condition Detector Pro IS may be

easily programmed for six alarm settings,

which include the alert and danger levels

for each of the three measurements. Whenmeasurements are taken, current

measured values are automatically

compared to six user-defined settings, and

the SKF Machine Condition Detector Pro ISs

alarm indicator and LED react appropriately.

An alert condition provides a user with an

early warning of impending problems for

which immediate in depth analysis should

be performed. A danger alarm indicates

that a problem has escalated to a point

where actions must be made quickly to

avoid a serious failure.

SKF MARLIN QuickConnect studs for

quality, repeatable data collection

Specially designed mechanical and

computerized studs enable one or several

users to collect consistent, accurate, and

repeatable data from each measurement

point. Engineered to work exclusively with

the SKF Machine Condition Detector Pro IS,

the SKF MARLIN QuickConnect mechanical/

computerized studs provide for a fast,

quarter turn connection which temporarily

fastens the probe to a measurement point.This reduces the possibility of errors and

inconsistencies often resulting from data

collected by a variety of individuals using

varying methodologies.

parameter for judging rotational andstructural problems like imbalance,resonance, misalignment, looseness,and stress applied to components.

Many machinery problems may causeexcessive overall vibration. Mechanicallooseness, imbalance, soft foundation,misalignment, rotor bow, resonance,eccentricity, bad belts, or lost rotorvanes can all be measured with overallISO (International Organization for

Standardization) vibration measurements.

Measuring the overall vibration of amachine or component, or the structure ofa machine, and comparing the measuredvalue to the machines normal value (or toISO 10816 standards) indicates machineryhealth and condition changes.

NOTE: Overall vibration is not an indicator ofbearing or gear mesh problems thattypically occur in higher frequencyranges.

Enveloped acceleration

Bearing/gear mesh frequency vibration(10 kHz to 30 kHz)

Enveloped acceleration measurementsmeasure the high frequency repetitivevibration signals typically caused bybearing and gear mesh problems.

Envelope detection is very useful in rollingelement bearing and gear mesh analysiswhere a low amplitude, repetitive vibrationsignal may be hidden by the machinesrotational and structural vibration noise.

For example, suppose a rolling elementbearing has a defect on its outer raceway.Each rolling element strikes the defectas it passes the defect, causing a small,repetitive vibration signal. This vibrationsignal is of such low amplitude that, undernormal ISO vibration monitoring, it islost in the machines other rotational andstructural noise.

Envelope detection filters out lowfrequency rotational signals, then enhancesthe high frequency defect signals to focus

Overview

A multi-parameter approach to conditionmonitoring provides two different methodsfor monitoring machinery condition.This allows for early detection of specificmachinery problems and provides moreways to measure changes in machinerycondition.

The SKF Vibration Penplusis a multi-parameter vibration monitoring tool

capable of measuring vibration (causedby rotational and structural problemslike imbalance, misalignment, looseness,etc.), and capable of measuring vibrationin higher frequencies (caused by rollingelement bearing or gear mesh problems).

Multi-parameter monitoring is themost thorough and effective methodfor monitoring bearing and machinerycondition. The Vibration Penplustoolsmulti-parameter approach providesaccurate and reliable data upon which tobase maintenance decisions and promotesearly detection, confirmation, and accurate

trending of bearing and machineryproblems.

Functional description

When performing measurements, theVibration Penplustools sensor input signalis processed to produce two differentmeasurements for each machineryPOINT, Overall Vibration and envelopedacceleration.

The Vibration Penplustools LCDsimultaneously displays both measurement

values. Depending on the type andlocation of the machinery componentbeing measured, either or both readingsmay be of interest.

Overall vibration

(ISO* 10816, Part 1-6) Low frequencyvibration (10 Hz to 1 kHz)

Overall velocity vibration occurring inthe 10 Hz to 1 kHz frequency band isconsidered the best operating

on repetitive events in the 10 kHz to30 kHz frequency range, and provides an

averaged peak value for early detection ofbearing and gear mesh problems.NOTE: Enveloped acceleration measurements

do not detect rotational or structuralvibration caused by imbalance,misalignment, looseness, etc.

Easy operation

Vibration Penplusreadings are easilyperformed, simply:

Turn the Vibration Pen pluson.Press the Vibration Pen plustoolssensor tip against your machinery

measurement POINT.Wait for the readings to stabilize, andrecord the measurement values.

Easy evaluation

The Vibration Penplustools front-panelLCD simultaneously shows overall velocityvibration readings in mm/s RMS (CMVP50) or in in/s equivalent Peak (CMVP 40),and acceleration enveloping readings in gE(E indicating enveloped acceleration).
