The painting thickness instrument gauge used on the various types of metals such as CS/ SS by
(Elcometer 204) device.
To measure the thickness of the paint applied to such a place, it is necessary to return to the technical speci fi cation which has been established where to the ASME code, in order to see if this measure is compacted or not.
to measure the quality of materials ..
The kind of acceptance for the site works is measured in terms of: 1. Compliance with the work plans or drawings, agreed work sequence and procedures or method statement. 2, Ensure that the work is being carried out in accordance with the project specification, code compliance (local, international or Authority having jurisdication), current plans, at expected quality and duration. 3. Ensure that permit to work is available and monitored in regular basis by a safety officer. 4. Work is manage by an engineer, a supervisor or foreman who knows very well the work being performed. 5. Work is verified and accepted by a quality control engineer.
Magnetic, eddy current, ultrasonic, & micrometer are the principles for coating thickness measurement.
Magnetic Type gauges are used to measure the non magnetic coating thickness on magnetic or ferrous substrate.
Eddy current Type gauges are used to measure the non conductive coating on conductive substrate
electro-magnetic principle
Coating Gauges are based on several principle such as magnetic, eddy current, ultrasonic, & micrometer measurement for cured coatings.
Electro Magnetic Induction and Eddy current principles. The substrate underneath the paint shall be conductor to measure the thickness.
Coating Gauges are based on several principle such as magnetic, eddy current, ultrasonic, & micrometer measurement for cured coatings. Usage of these gauges is depend upon the type of coating, the substrate material, the thickness range of the coating, the size and shape of the part.
Electromagnetic induction is used for non-magnetic coatings on steels, eddy current is used for non-conductive coatings on non-ferrous metal substrates.
