2Customer Requirements and Device Specification

Measuring the coating thickness early inthe process is the key to documenting and

controlling in-line coating processes, saving on coating material, improving coating quality,

and reducing running-in time and scrap. Coating processes are highly sensitive to changes

in environmental conditions; therefore, it is crucial to have access to a thickness gauge that

is easy tohandle and works in an industrial environment.

The patented measurement process used by the coatmaster® Flex is non-contact (as

opposed to systems based on magnetic induction or ultrasound) and non-destructive. It can

therefore be applied on wet, powder, and cured coatings, independently of the coating

material, thickness, or colour (including white). Incontrast to magnetic induction-based

systems, the Flex device permits measurement ofcoating thickness on substrates such as

metal, wood, plastic, and rubber. Unlike photothermal, laser-based, and ultrasound

systems, it is a reliable, light, user-friendly, safe,cost-effective, precise, and accurate

measurement system. It requires minimal calibration and is insensitive to the angle and

distance of measurement.

3Applications

The coatmaster® Flex is a flexible and robust handheld device for non-contact

measurement of coatings.

The coatmaster® Flex is unique and versatile and can be used in a wide variety of industries

and industrial sectors:

•

Automotive

•Rail

•Aerospace

•Marine

•

Construction

•Furniture

•

Turbines

•Wind Power

•Pipelines

•Medical/Technical

The coatmaster® Flex is particularly suitable for the following applications:

Powder paints

Due to precise control of coating thickness, up to 30% of the powder

quantity can be saved. Measurement early in the process saves time and

reduces rejection rates.

Wet paints

Precise measurements are possible even before drying. The measuring

equipment capability is guaranteed. This saves material and time, and

ensures quality.

Coil coating

The coatmaster® brings the coating process for coils into the target range

after only a few metres. Savings of coil and coating material pay for

themselves within a few months.

4Functionality and Measuring Principle

The coatmaster® works according to theprinciple ofthermal layer testing (TLT). The

surface of the coating is heated with alight pulse. After brief heating by afew degrees

Celsius, the surface is cooled by heat conduction todeeper areas ofthe coating and the

substrate. The cooling process on the surface depends on the thermal properties of the

coating and the substrate. The thinner the coating, the faster the surface temperature

decreases, providing it has a lower thermal conductivity than thesubstrate. Thethickness

and thermal properties of the coating are derived from the dynamics of the surface

temperature.

Generally, coatings have a very irregular surface. Powder coatings before curing have an

even rougher surface, but can nevertheless be measured with the coatmaster® Flex. The

properties of this roughness are influenced by various factors, such as pre-treatment, the

type and roughness ofthe substrate, the type ofcoating (e.g. particle size, distribution, and

chemical composition), and the exact conditions (temperature distribution, baking time)

during baking. The figure below shows a microscopic sketch of this roughness.The TLT

automatically compensates for the roughness described above, using an optical averaging

process. This allows areliable determination ofthe coating thickness, even with changing

parameters.

5Safety and Responsibility

This section provides an overview of all relevant safety features for optimum personal

protection and safe and trouble-free operation. Keep the operating instructions with the

safety instructions so that you can refer to them later.

5.1 Warning Symbols

For your safety, it is important to read and fully understand the following table showing the

different warning signs and their definitions!

5.2 Signs and Icons

Symbol Definition

This symbol means that your device meets the safety requirements of all

applicable EU directives.

This symbol means that you may only dispose the device at an approved local

disposal site.

Information: a highlight containing particularly important information for better

understanding.

5.2 Intended Use

The coatmaster® Flex is intended exclusively for the measurement of coating thicknesses.

The device should only be used as a handheld device.

The device should not be mounted on a robot or fixture, or operated for an

extended period of time.

The instrument may only be operated and cleaned by trained personnel. The intended use

also includes compliance with these instructions and the maintenance intervals must be

observed.

Have your device repaired only by qualified personnel and only with original spare parts.

This ensures that the safety of the device is maintained.

The device is not approved for operation in environments with potentially explosive

atmospheres.

Keep the device away from rain or moisture. Penetration of water into an electrical

appliance increases the risk of electric shock. Do not place the measurement device in a

place where components could come into contact with corrosive gases or salty air.

Do not block ventilation openings. The ventilation openings prevent the interior of the unit

from overheating.

Remove the battery before cleaning. Do not use solvents for cleaning, to avoid damaging

the housing surface. Use a clean, dry cloth.

In accordance with Directive 2012/19/EU, please take old parts to the appropriate recycling

facilities for proper disposal, reprocessing, and reuse. Never throw electrical equipment

into the household waste! By properly disposing of the electrical appliances, you help to

protect valuable resources and prevent possible negative effects on health and the

environment, which could otherwise occur due to improper waste disposal. Accessories and

packaging should also be recycled in an environmentally-friendly manner.

5.3 Improper Use

Use not mentioned above, or use that does not comply with the technical specifications, is

considered to be improper use. The operator is solely responsible for any damage caused

by improper use.

The following applications are prohibited:

•Use of the equipment in environments where liquids may get into the device.

•Introduction of any objects into the coatmaster® Flex or similar devices.

•Opening of the device, except for cleaning or changing filters and changing the

plexiglass pane. This only applies when the battery is not in place. Opening the

device, other than for standard maintenance operations (see section 11), voids the

warranty and the manufacturer assumes no liability.

The following safety instructions point out dangers of a general nature that may occur when

handling the device. The user must observe all the instructions listed in order to minimise

possible hazards.

Additional warning messages can be found in this manual whenever the actions described

could result in hazards.

Symbol Description

WARNING

Integrated light source.

The coatmaster® Flex contains a 125Ws Xenon flash lamp, which falls under

risk group 3 according to the photobiological safety standards of IEC

62471:2006. The coatmaster® does not emit harmful UV radiation.

When pressing the trigger button to conduct a measurement, a flash –

comparable to a studio flash – is released. Hazardous optical radiation could

be emitted in circumstances of direct and close eye contact. Visual

impairment or eye injury may result.

◊Never look directly into the light source.

◊Never point the light source towards a person in the near vicinity.

◊For the use of the coatmaster® Flex in an operating process

environment, we recommend establishing protective measures (e.g.

opaque cover) to limit any risk of direct exposure to the flashlight.

◊Use the coatmaster® in a well-lit environment.

CAUTION

Device damage may occur if the battery is changed during operation.

Never change the battery during operation, as this can lead to the device being

damaged.

◊Always switch off the device before changing the battery.
