INTRODUCTION

The Recognoil device enables the user to detect residual oil / grease contamination on the surface of the material.

It can be used with almost all oil types and lubricant residues, which contain a part of a synthetic compound. It is not suitable for very refined mineral oils – these applications often require a fluorescence agent. The Recognoil device is not suitable for use with silicone oil based compounds.

Recognoil integrates a source of UV radiation and a fluorescence detector. Together with a personal computer, connected via USB, it is able to create, evaluate and to display the surface’s detected properties within a few seconds.

The Recognoil Software is designed to run on Microsoft® Windows™ XP, Vista, 7 and 8 machines.

3.5. Detection walkthrough

Plug the supplied USB cable into the device and then into a USB2.0 port of your computer.

! Please DO NOT plug the USB cable in a USB 3.0 port ! (unless there is no 2.0 port present)

Run the Recognoil program (Recognoil 2.2.1)

Prepare the object and put the Recognoil device facing down on the surface.

1. switch on the device

The device will be switched on automatically upon correct USB connection.

2. detector activation

If the detector serial number is correct, you can now choose one of two detection modes:

3. LIVE preview

(only for Professional Edition)

Click the “LIVE” button (or hold the trigger 1.5 to 4 secs.) for a real-time video feed of the irradiated surface. Put the device on the surface. Press and hold the trigger to begin. Exposure time is automatically selected. The result values are displayed in the bar graph diagram on the right hand side. The mode will be quit after touching the “LIVE” button again. If the device is detecting big amount of light entering the detector, it will stop working for the reason of personnel safety – risk of eye damage when viewed directly in to the UV source.

4. choosing the surface contamination

This step is optional. The oil files are loaded in the /Recognoil/OilDB/ directory. Choose “LOAD OILS” to show the list. After the oil has been chosen from the list, the surface concentration and layer thickness values are shown.

Warning – the resulting values of surface concentration and layer thickness are strongly dependent on the substrate layer. Please be careful when interpreting the results.

5. Activating Photo mode

Click on the PHOTO button or touch the trigger (0.2 to 1 sec). Put the device onto the surface and press the trigger. Please do not move the device during the scanning procedure (3-5 seconds).

6. Standard mode

The standard mode offers automatic intelligent sequence detection.

7. ALD mode – ambient light deduction

In case of improper light shielding, the detector switches itself in to the ALD mode. The detection now takes double the time, but the ambient light is eliminated. This function has its own limit of the amount of light that can be deducted. When the limit is exceeded, you will be noticed that the exposition could not be finished.

8. Manual mode

In case of the automatic mode is not applicable, i.e. in need of very long or very short exposure times, you can click the MAN button and manually set the exposure time. This function also finds out, whether to use intelligent light deduction or not.

Page 15

Recognoil – User‘s Manual

Software version 2.2.1_2015-02-21

9. ALD always on

If you want to use light deduction all the time to ensure the very same results at all condition, you can turn this function on in the Settings dialog.

10. Contrast adjustment and area of interest selection

After the detection has been executed, you may now wish to adjust the contrast, because the main window shows most likely a black area with a few bright dots. These are locations with maximum grease layer thickness, or, dust particles. Move the contrast slider downwards to show the smaller layer thicknesses. After that you may choose an area of interest by clicking, holding, moving and de-clicking the display or the mouse button. The outcome is then computed only for this selected area. The contrast slider may be locked to an exact value, e.g. when performing scans of similar samples – to see the color differences. Exposition lock is activated by clicking the “Lock” icon.

11. Dust particles deduction

(only for Professional Edition)

In the Professional version, you may use the second slider to lower the influence of the dust particles. Please do this option only if you are sure, that it’s about dust. The detector output outcome changes accordingly.

It is recommended to get the object’s surface disposed of any dust particles prior to the

detection. Please use dry compressed air, preferably in pressurized cans suited for electronics cleaning.

12. Protocol JPEG / BMP / GIF Save

After every detection, you may export the values and image data by clicking the second icon from the Menu.

• Validation - calibration module: Please see chapter 6.

• Working directory: click Change if you want to choose other directory, which

contains oil files, RAW files and Result files.

• Manual exposition – in case of need of very short or very long exposure times, use this option. The Detector output outcome may not be the same as in the automatic intelligent mode. For advanced users only.

• You can disable the button sound effects by un-checking “Button sound effects”

• Save RAW images – the default setting is ON – the software records every detection

into a RRW file, which can be later opened and evaluated. Every files has approx.

0.5 Mbytes.

• Always use ALD option – in automatic intelligent mode, the ALD method is activated, when there is the environment light getting to the detector. If you want to use this mode every detection, regardless on this amount of light, check this option. The detection then takes twice the time

5. PRACTICAL INFORMATION

Table of applications:

chart 1.: area of suitable applications

Please note that it is not possible to detect oils of silicone nature.

5.1. Principle of operation

To get the fully trusted results and outcomes of the Recognoil device, it is important to get to know the basic principles of device operation.

The device irradiates the surface with invisible and undetectable UV light. The certain physical and chemical properties of the residual grease and oils force the chemical elements and molecules to emit visible light. This natural phenomenon is called fluorescence. Now we are getting close to the first limitation of this method.

The first limitation

The UV source, as mentioned above, emits invisible and undetectable radiation. On the other hand, the detector then receives the outcomes of the fluorescence process, which emit radiation in the domain of visible light. If there is a light coming from the environment, not originating from the process of fluorescence, it interferes with the fluorescence signal and disrupts the detection. For this reason, detections need 100% lightfree environment. The exceptions are described later in this section.

The second limitation

The detector consists of a small detecting plate, which converts the incident light into electrical signal, which is then analyzed by the software. Because of the need of transferring the light from a bigger surface onto this very small detecting plate, a set of lens must focus the incoming light. Every lens has a focusing point. The Recognoil device has a fix focusing point, which cannot be changed. The second limitation limits the allowed distance of the object within +/- 3 mm far from the focusing point.

The goal of a successful detection is to find the ideal conditions – to eliminate the environmental light and to find the ideal distance of the desired surface.

Page 22

Recognoil – User‘s Manual

Software version 2.2.1_2015-02-21

NOTE

Please do not use paper towels or cloth containing industrial bleachers for manual degreasing, as they can influence the result values. Bleacher can be transferred to the object’s surface when using solvents. Since the bleachers present a very high fluorescence activity, the result values of the Recognoil detection may be much bigger than the actual amount of oily residues on the surface.

5.2. Methodology

Detection of grease residues with the Recognoil device on objects of different shapes and sizes

This section has been written for the reason of two basic existing limitations of the Recognoil device. First – the need of exact distance of the object and the Recognoil detector head, second – the need of 100% light out-screening. The Recognoil device is primarily designed for planar objects of bigger dimensions, but, with the help of this manual, the number of possible applications can be made considerably greater.

1. Objects with planar surface with dimensions greater than 100x50 mm

E.g. sheet metal, ALU profiles, etc. Detection may be performed directly by putting the detector head to the surface. Note 1: Even though the detection itself is called non-destructive, it is to be remembered, that the Recognoil device touches the surface with a rubber profile, ensuring that no light can get inside the detector head. If this rubber profile has been contaminated by touching a highly polluted surface, it will hand over the residues to a surface, which is cleaner, causing unwanted contamination. Please remember, that this may damage the sample in a way that it cannot be used in the production any further and must be degreased again. For this purposes it is recommended to use multiple “detector head protectors” – one for the “polluted” surface, one for the “supposed-clean” surfaces. Note 2: Due to undesirable reflections of the UV radiation directly to the main detector aperture, there may, in case of low oil film and in case of high contrast amplification, emerge unwanted elongated shapes, which do not denote elevated oil film thickness, but the undesirable UV reflection. For this reason, we recommend to perform these detections in a “cross-align” or “diagonal-align” way to minimize the influence of these effects. Please see the Appendix of this document.

2. Objects with planar surface with dimensions smaller than 100x50 mm

E.g. sheet metal samples, cutoffs, etc. Again, the detection may be performed directly, but the sample must be placed on an appropriate clean metal surface that it does not influence the detection outcomes. The unwanted background surface can be neglected by selecting the appropriate surface in the software. As the underlying object it is recommended to use a black anodic oxidized aluminum sheet metal due to its low reflectivity and high absorption. In case of higher

Page 23

Recognoil – User‘s Manual

Software version 2.2.1_2015-02-21

amount of usable samples, there can be more of them laid next to each other, creating an appropriate surface size.

3. Objects with a curved surface with radius R > 400 mm

E.g. steel wheels for railway transport, etc.

Detection can be performed directly, but if there is light detected, coming from the environment, the ALD exposition type is automatically executed. It takes twice the time, but it can eliminate the influence of the light. The focusing distance may also come to the point, but for the radiuses greater than 400 mm, the influence is neglectable.

4. Objects with a curved surface with radius R < 400 mm

The oil film detections of these objects may suffer from poor focus of the detector. Due to this issue, we recommend using a special-designed “detector head protector”, copying the surface curvature and setting the right focusing distance.

5. Wire, a circle-shaped cross section profile with diameter up to 2 mm

This type of object can be detected directly, putting the detector head on to the wire, which has been laid on an appropriate underlying surface. Again, a black anodic oxidized aluminum metal sheet is recommended for these purposes. It is recommended to place the wire in a “diagonal-alignment” to minimize the effects of unwanted UV radiation reflections, influencing the results.

6. Wire, a circle-shaped cross section profile with diameter greater than 2 mm

Under certain circumstances, the wire can be detected directly, but there will be an ALD type exposition automatically executed to minimize the influence of the environment light.

7. A complex-shaped object with the longest dimension not exceeding 200 mm

For this purposes, there is a special product called “black-box”, which is a closeable box, made of a black anodic oxidized aluminum metal sheet, in which there is the object placed. The Recognoil device is put on the other side and secured in its place. The object is placed in an adjustable holder, to be allowed to set the appropriate focusing distance.

8. A complex-shaped object with the dimensions exceeding 200 mm

There is no special recommendation for detection of these types of objects. It is recommended to find and use the most even surface, while the detector is in ALD mode. There are some advanced techniques developed right now, to scan the surface in realtime, without the need of special light out-screening.

Page 24

Recognoil – User‘s Manual

Software version 2.2.1_2015-02-21

5.3. Examples of use

For the purposes of demonstration, we can suggest 3 spheres of the device application.

Example 1 – a paint shop

The Recognoil device serves as a quick random check of the surface degreasing quality. The operator has already found out, what limit settings are appropriate for the type of object being detected. A value of detector output, together with a per cent value, which shows how big part of the surface has grease / oil amounts exceeding the limit, are displayed 2 seconds after the trigger has been pressed.

Example 2 – a laboratory

A laboratory would need to know exact surface concentrations and layer thicknesses. For this reason, the one and only oil / grease type must be present on the surface and the substance must be “sampled” in our laboratory. After this sampling process, we send an “oil file”, which is then imported into the software and the results are from that time represented in surface concentrations and layer thicknesses.

Example 3 – sheet metal factory

In a sheet metal factory equipped with a degreasing line, an operator would check at which state the material goes into the degreasing line and then would check the output. The operator has already the knowledge, how much DO (detector output) shows the Recognoil device after degreasing at a normal state. When the device begins to show greater numbers and shows areas of brighter colors on the display (selective accumulation of the grease residues), it is a warning for the operator, that the degreasing line is faulty.

5.4. Notes

Even with the best degreasing method ever, it is not possible to get lower detector output outcomes than approx. 50 units. This value strongly depends on material roughness and anisotropy, together with the material constitution (value 50 for steel, value approx. 80 for aluminum). The value 50 consists of basic fluorescence properties of the material (and its oxides) plus non 100 per cent exact device radiation filtering, which then causes noise, visible at large amounts of amplification.

For very precise detections, it is recommended to use always the same set of materials with the same roughness as a reference sample.

If you are working with objects that contain smooth curved surfaces, it is possible that “direct reflections” happen. Under certain angle, the incident UV ray bounces off directly into the detector aperture, causing a small brighter elliptic-shaped area, which acts as detected oil or grease.

6. VALIDATION - CALIBRATION

(Professional version only)

In case of Recognoil Professional version, an aluminium sample validationcalibration sheet has been delivered to you, allowing you to perform validation test periodically.

Validation procedure can be executed from the Settings menu.

Please follow the instructions of every step.

In the final step, the resulting value is shown. If the value is much bigger than the preset sample value, it is necessary to clean the device. Please click “Cleaning instructions”.

If the value is smaller, it is recommended to perform calibration, clicking the Calibration button.

Page 26

Recognoil – User‘s Manual

Software version 2.2.1_2015-02-21

Recognoil device calibration dialog

If the validation procedure has indicated that the calibration is recommended, you may use the same sample to calibrate the device.

The calibration utility automatically makes a couple of detections with different settings and at the end, it chooses the best options.

The method is easy to accomplish and starts with the sample preparation.

1) Remove the foil from one part of the metal surface and right at the moment, place the Recognoil device on to this surface.

2) Click the Execute the calibration sequence button. After that, follow the instructions.

3) The calibration process takes up to 60 second to complete. During this time, you are obliged to hold the device in a steady position, without any movement.

4) After the calibration process has finished, the calibration results are displayed. After that, you can press the Save and write to EEPROM button, which records the settings permanently in to the device memory.

5) After a successful save, please restart the application for the changes to take effect.

Please note:

a. the part of the sheet metal, from which the foil has been removed, cannot be used

anymore. The reason is mainly the dust and the surface changes after being exposed to the air and the light. In some cases, the sample can be re-used, if it has been instantly tightly covered with plastic foil after use and kept at r.h. up to 50%.

b. the calibration has to be executed immediately, after the foil has been removed
