The Smart Way ToMeasure Coating Thickness

HELMUT FISCHER offers you signi-ficant advantages for all coatingthickness measurement applicationswith its new family of electromag-netic hand-held instruments.The modular design of the systemcomponents offers• differently equipped instrument

models• for measurements according to

both the magnetic induction and the Eddy current methods

• with a broad selection of different probe models.

The coating thickness measuring instru-ment best suited for a measurementapplication can be selected dependingon the application itself and the demandfor measurement data processing anddocumentation.

Regardless of the instrument you choose, you receive• a powerful, state-of-the-art instrument• that is highly accurate,• easy and uncomplicated to use• measures a broad range of applica-

tions.

The large LCD display – by default inall instruments available – not onlyfeatures a large display of the readingbut informs the user about all essen-tial measurement parameters.

In addition, context-sensitive infor-mation notes on two display lines,simplifies the use of the instrument.

System FISCHER®

Hand-held instruments operating accordingto the magnetic induction and Eddy currentmethods have become the industry stand-ard for fast, accurate and nondestructivecoating thickness measurement on steel ornonferrous metals. Use of these portable,light-weight hand-held instruments hassteadily increased, particularly where corro-sion protective coatings are involved.

Why take measurements?

One of the most important quality criteria insurface finishing is the adherence to definedcoating thickness specifications. Qualitycontrol is imperative for both suppliers andpurchasers for obvious reasons.

Which coatings can be measured?

• Nonmagnetic coatings on ferromagnetic substrates (using the magnetic induction method according to DIN EN ISO 2178, ASTM B499), e. g., zinc, chromium, copper, tin, or paint, plastics, enamel on iron or steel.

• Electrically nonconductive coatings on nonferrous metals (using the Eddy cur-rent method according to DIN EN ISO 2360, ASTM B244), e. g., paint, enamel, or plastics on aluminum, brass, or zinc and anodic coatings on aluminum.

Depending on the probe and instrumentused, coating thicknesses can be measuredin ranges up to 25 mm (1.0“). In someinstances, even thicker coatings can bemeasured (up to 70 mm/2.75“).

Who can make measurements?

Neither special skills nor special knowledgeare required. Particular emphasis has beengiven to a clear and unambiguous displayand instrument design and to easy key-board operation. If special questions ariseconcerning an application, FISCHER iscommitted to assist, both with specific infor-mation and through FISCHER seminarsconducted on a regular basis.

How long does a measurement take?

It only takes a few seconds. If no calibrationis required, the operator only needs to posi-tion the probe, read the coating thicknessmeasurement, and if applicable, save theresult with the push of a button. Measure-ment data storage enables immediate statis-tical evaluation of the measurement series.

How are measurements taken?The measurement probes contain pick-upelements which generate the magnetic in-duction or eddy current probe signal. Theprobe is placed on the test specimen andsupplies the signal which is proportional tothe coating thickness to the instrument.The measurement signal is processed,displayed and evaluated by the instrumentand may also be transmitted to other de-vices via a serial interface. Calibration pro-cedures take the application specificmeasurement conditions into account.

Where can you measure?

Practically anywhere. The entire system(consisting of the instrument and theprobe) is small, pocket-sized and highlyportable.

There is no need for an external electricalpower supply; the instruments are readyto take measurements at any time.

This enables in the most simple way mea-surements on site, for example, the deter-mination of the thickness of anodized coa-tings on aluminum parts of house facadesor of paint or zinc coatings on steel con-structions (see image on the title page).

Measurement Capture

An assortment of smart probes for variousapplications is available. A selection isshown in this publication.

Each FISCHER smart probe consists of ameasuring element, a memory chip, and aconnector. The measuring element suppliesa signal relative to the coating thickness; thedesign and shape of the probe are depen-dent on the measurement conditions. Cali-bration data are stored in the memory chip.This makes an application specific calibra-tion residing in the probe itself. Finally, theconnector allows for a quick and easy con-nection to any of the available FISCHERhand-held and bench top instruments.

Measurement Data Output

The FISCHER system offers the followingoptions for measurement data output:• Data display choices: Depending on the

instrument version, single readings or batch mean results and statistical evalua-tion data can be displayed.

• Instruments with serial interface can be connected to a PC and integrated into a data network or to a printer.

Measurement Processing

A total of six basic instrument versions areavailable:

LCD Display

Hand-held instruments cover a broad rangeof application-specific measurement tasks.The first criterion for instrument selection isthe coating/substrate material combination.The magnetic induction method is used fornonmagnetic coatings on iron or steel; theeddy current method for electrically non-conductive coatings on nonferrous metals.The FISCHER program offers a completefamily of instruments for both test methods:magnetic induction instruments have themodel names DELTASCOPE® and PERMA-SCOPE®, Eddy current instruments thename ISOSCOPE®. The DUALSCOPE®

includes both test methods.

The functions and features integrated in theinstrument provide another selection criteri-on. The display of the measurement may besufficient for some applications. More fre-quently the measurement data needs to bestored and evaluated according to certaincategories. The data storage feature allowsfor the full statistical evaluation of the meas-urement series by the instrument. For themost demanding applications, the operatorrequires a hand-held instrument with thepower of a laboratory grade measurementsystem. Even such an instrument is avail-able from FISCHER.

ISOSCOPE® MP0RDUALSCOPE® MP0R and MP0RHDUALSCOPE® MP0R-FP and MP0RH-FP

The instrument versions MP0R and MP0RHare available if the accessibility of the mea-surement area does not require a separateprobe. However, if measurements are to be made on parts with complex shapes,requiring a simple instrument consistentlywith the same measurement probe type,then the MP0R-FP or the MP0RH-FP arethe ideal choice.

• The ISOSCOPE® MP0R is used to mea-sure paint, lacquer, synthetic or anodizedcoatings on all NF-materials such as alu-minum, copper, brass and on stainless steel

• The DUALSCOPE® MP0R or MP0R-FP are used to measure NF-coatings (e.g. chrome, copper, zinc) on iron and steel aswell as paint, lacquer, enameled or synthetic coatings on iron and steel or on nonferromagnetic metals

• DUALSCOPE® MP0RH or MP0RH-FP for the measurement of electricallynonconducting coatings with severalmillimeters thickness on steel or on nonferromagnetic metals.

DUALSCOPE® MP20E-S

DUALSCOPE® MP20E-S

This instrument uses both the magnetic in-duction and the Eddy current test method.If coatings are to be measured on ferro-magnetic and nonferromagnetic metal substrate materials, and if one applicationmemory is sufficient, then the DUALSCOPE®

MP20E-S provides a very low-cost solutionfor an instrument with plug-type probes.The instrument features the following mea-surement capabilities:

• NF metal coatings of zinc, chromium or copper as well as paint, enamel or plasticcoatings on steel and iron.

• Paint and plastic coatings on NF metals or stainless steel and anodized coatings on aluminum.

The DUALSCOPE® MP20E-S includes abidirectional RS232 interface. The measure-ments of a measurement series can be stored, evaluated according to popular sta-tistical methods, and output to a printer ortransferred to a PC. Minimum, maximum,mean value and standard deviation are dis-played with the push of a button. The num-ber of measurements in the current testseries appears on the display in addition tothe coating thickness reading.

Normally the instruments are immediatelyready to measure. Normalization by meas-uring the uncoated part is generally suffi-cient when switching to a new measure-ment application involving the same sub-strate material but different geometry andtest area. Use the ZERO function to deter-mine the new zero point to quickly establisha valid calibration. If the ferromagnetic pro-perties of the material change, use the CALfunction to adapt the calibration to the newmaterial. This requires the use of one or twocalibration foils in addition to the bare sub-strate measurement. The calibration isstored in the probe and is available forimmediate recall at any time.

Characteristic Features:

• Large LCD display for measurement and evaluation data as well as icons for statusdisplay and operation notes on display lines.

DUALSCOPE® MP40E

DUALSCOPE® MP40E-S and MP40E-R

DUALSCOPE® MP40E combines the magne-tic induction and Eddy current methods inone hand-held instrument, similar to theMP20E-S. This combination enables theuser to measure in random order paint, pla-stic, and organic coatings on nonferrousmetals and on steel, and nonferrous metalcoatings (such as chromium, copper, zinc,etc.) on steel with one and the same instru-ment. The attributes of the DUALSCOPE®

MP40E correspond to the ones of the MP30E models. Measurement data can bestored according to an application. Measure-ment series can be printed out or transferredto a PC.

These models also use plug-in type smartprobes. A probe suitable for a particularapplication is connected easily and quickly.The instrument recognizes whether a mag-netic induction or an Eddy current probe isconnected. If a DUAL probe is used, theinstrument even recognizes the material andselects the appropriate measurementmethod according to DIN.

The DUALSCOPE® MP40E-S features a bi-directional RS232 interface. This permits the transfer of measurement data from theDUALSCOPE® MP40E-S to a PC, for in-stance to generate a control chart withSPC/SQC software. The instrument can alsobe controlled entirely from a computer. Thekey functions can all be addressed via theRS-232 interface allowing for remote controland integration of the instrument in a fullyautomatic measurement system.

System Fischer: Standard Smart Probes

Standard Probes

The probe supplies a measurement signalrelative to the coating thickness. Properprobe selection and the quality of the probedetermine the accuracy of the measure-ment for any particular application.

Within the FISCHER System, every smartprobe works with every instrument (pro-vided that the measurement method ofprobe and instrument are the same). Thisunlimited ability to combine allows the ope-rator to cover diverse measurement appli-cations simply by changing probes.

The many different applications requireprobes of different design and shape. TheFISCHER System family of smart probesincludes many different designs. A generaldistinction can be made between standardprobes and custom probes. FISCHERdevelops custom probes for specific meas-urement applications that are not coveredsatisfactorily by standard probes. The com-pany’s application engineers are constantlyworking on new solutions.

When using a standard probe, model se-lection is determined by a number of crite-ria. The first criterion is the coating/subs-trate material combination. This determinesthe measuring method of the probe – Eddycurrent or magnetic induction. The use ofdual measurement probes are increasingin popularity. They operate according toboth measurement methods and can beconnected to either the DUALSCOPE®

MP20E-S or MP40E. The EDX10 probe is designed for the measurement of dual layers (paint or laquer/zinc-layer on iron).The table to the right features a selection of available probes.

Geometric conditions of the measurementarea determine the shape of the probe.Radial, axial, and right angle probes areavailable. The ETD3.3 Eddy current probe is ideal for curved surfaces. This uniqueprobe gives correct thickness readings even on curved surfaces.

In the end, the probe that promises theoptimal result is determined by a number ofother aspects. Very important are the thick-nesses of the coating to be measured andof the substrate. Coating hardness and surface roughness needs to be taken intoconsideration; often, two-pole probes exhibit better results on particularly roughsurfaces. Other considerations are the cur-vature and size of the measurement area.

Version MP10E offers no capacity for storing measurements.

With all instrument versions, the mastercharacteristic is stored permanently in theprobe plug.

Bi-directional data transfer between theMP20E-S, MP30E-S or MP40E-S and aPC enables measurement data acquisitionand storage on the hard disk of a PC. Inaddition, all key functions of the instrumentare available from the computer for remotecontrol applications. This allows for inte-gration of the instrument in a fully automa-ted measurement system. For instance, ifthe geometry of the test area changes, therequired application can be selected, and the correct test area specific calibrationcan be made available automatically. Withthe unidirectional radio interface of theinstrument version “R”, measurement datacan be transferred wireless to a PC acrossdistances of up to 20 m.

Instrument versions with serial inter-face offer the possibility of application-specific data management andSPC/SQC software data acquisitionwith external PC.

This results in a separation of supervisorand operator functions.

System FISCHER: Calibration, Data Storage

Measurement data storage capabilityThe MP30E and MP40E model series havetwo basically different measurement datastorage modes:In the Standard Measurement Data Stor-age Mode single measurements are takenconsecutively on the same part by the oper-ator, for example on a screw head, and arethen grouped with BLOCK-RES into a localmean. The resulting mean value then repre-sents the local coating thickness of the signi-ficant surface according to ISO 2064. Thismeasurement data storage mode is espe-cially well suited for the coating thicknessmeasurements of electroplated coatings.

Measurement Data DocumentationThe bi-directional RS232 interface of the"S" version, which can be configured to different peripheral instruments, offersextensive documentation possibilities. It ispossible to print individual readings, withstatistical evaluation, histogram, as well asCp- and Cpk indices during the measure-ment process, as well as at a later time.Block results and final results are printedwith date and time. Using the RS232 inter-face or using a radio transmitter of the "R"versions, all measurement data can betransferred to a PC for further evaluation.

In the Matrix Measurement Data Stor-age Mode the number of applications andblocks are predefined. Consecutive meas-urements can be stored in different, indivi-dually selectable applications and blocks.This measurement storage mode is ideal for coating thickness measurement appli-cations, where different parts have to bemeasured always on specific surface areas,and where the measurement data from thecorresponding surfaces are to be groupedinto sequential blocks. This measurementmode is used for example in the automo-bile industry, steel construction, etc.

Measurement data can be stored by the PC.

BLOCK-RES calculates statisticaldata for the current measurementseries. Date and time are stored.

All individual readings, measurements Blocks,as well as individual Blocks with statisticalparameters, histograms, etc. can be printedimmediately during measurement or at a laterdate.

FINAL-RES calculates statistical parameters forall stored measurements including blocks of anapplication. If product specification limits areentered the number of measurements violatingthe limits is shown. With fixed number of meas-urements per block, Cp and Cpk are also cal-culated.

Custom Designs, Fixturing Devices

The term custom designs covers specialdesigns and problem specific solutions.The common thread is the electromagne-tic measuring method. There are differentreasons to develop custom designs, forinstance:• Special probes become necessary

when the standard probes cannot be used – for any number of reasons.

• Custom designs may help, if position-ing of the probe on the surface to be measured proves problematic.

• Special fixtures can help to make measurements more efficient; this may lead to custom designs.

• The electromagnetic measuring method can also be used for applica-tions not related to coating thickness measurement, for example the meas-urement of the total thickness of a sheet or foil material. This requires spe-cial devices, in this case a suitable metal backing plate or roller.

So far, FISCHER has developed manycustom designs. A few examples are list-ed below. The number of custom designsincreases constantly.• Low profile two-pole probe to measure

coatings on the inside of small diameter bores or tubing.

• Special probe for thickness measure-ment of plastic coatings on female threads.

• Fixturing device V5GW2/TW3 for right angle probes to take measurements in hard to reach areas.

• Measurement fixture for screws to measure the thickness of electroplated coatings on metallic fasteners accor-ding to DIN ISO 4042 using the magne-tic induction method.

• Piston ring measuring table V4EKB4 to measure chromium coatings on piston rings and oil rings.

• Measuring stand V12 with magnetic sliding table for accurate small parts positioning.

• Measuring stand V12-AM with automa-tic probe positioning. Through soft touch positioning, even thin and soft paint and organic coatings can be measured accurately and reproducibly.
