Diferența între F, N, și FN acoperire grosime gabarit
F standuri pentru feroase feroase feromagnetice substrat. Tipul F acoperire grosime gabarit adoptă principiul de inducție la măsura neferomagnetic acoperiri și acoperiri pe feromagnetic metal substraturi astfel ca oțel și fier, astfel ca: vopsea, pulbere, plastic, cauciuc, sintetic materiale, fosfat strat, crom, zinc, plumb, aluminiu, staniu, cadmiu, porțelan, email, oxid strat, etc.
N standuri pentru Neferoase neferoase substrat. N-tip acoperire grosime gabarit adoptă principiul of eddy current; to measure the email, cauciuc, vopsea, plastic layer, etc. on cupru, aluminiu, zinc, staniu și altele substraturi cu eddy current sensors.
The FN type coating thickness gauge adoptă both the principle of electromagnetic inducție și the principle of eddy current. It is a two-in-one coating thickness gauge of F type and N type.
Function: Measure the thickness of the non-magnetic coating on the magnetic conductive object and the non-conductive coating on the non-magnetic metal substrate
Aplicare: Utilizare magnetic senzori la măsura non-feromagnetic acoperiri și acoperiri pe feromagnetic metal substraturi astfel as oțel și fier, astfel ca: vopsea, pulbere, plastic, cauciuc, sintetic materiale, fosfat strat, crom, zinc, plumb, aluminiu, staniu, cadmiu, email, email, oxid layer, etc. Use eddy current sensors to measure enamel, cauciuc, paint, plastic layers, etc. on cupru, aluminiu, zinc, stan, etc. substraturi. Widely used in manufacturing, metal processing, chemical industry, commodity inspection and other testing fields.
How to use the coating thickness gauge, points for attention
1. Magnetic grosime măsurare metodă: It is potrivit pentru măsurare the grosime of the non-magnetic layer on the magnetic conductiv material. The magnetic conductiv material is general: oțel\iron\silver\nickel. This method has high measurement accuracy
2. Eddy current thickness measurement method: suitable for measuring the thickness of non-conductive layers on conductive metals. This method is less accurate than magnetic thickness measurement method
3. Ultrasonic grosime măsurare metodă: At prezent, acolo este nu astfel metodă in China to measure the thick of the coating. Some outside manufacturers have such an instrument, which is potrivit for the measurement of the thick of the multi-layer coating or the occasion where the the above two methods cant be measured. But the general price is scump and the measurement accuracy is not high.
4. Electrolytic thickness measurement method: This method is different from the above three methods. It does not belong to non-destructive testing and needs to destroy the coating. The general accuracy is not high. It is more troublesome to measure than other types
5. Radiation thickness measurement: this kind of instrument is very expensive), suitable for some special occasions.
