What do F, N, and FN represent in a coating thickness gauge
The coating thickness gauge can non-destructive measure the thickness of non-magnetic coatings on magnetic metal substrates (such as steel, iron, alloys, and hard magnetic steel) (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) and the thickness of non-conductive coatings on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.) (such as enamel, rubber, paint, plastic, etc.). So what do F, N, and FN represent in the coating thickness gauge? Shenzhen Yuanhengtong Technology Co., Ltd. will provide you with a detailed introduction:
F represents ferrous ferromagnetic substrate. The F-type coating thickness gauge uses the principle of electromagnetic induction to measure non ferromagnetic coatings and coatings on ferromagnetic metal substrates such as steel and iron, such as paint, powder, plastic, rubber, synthetic materials, phosphating layer, chromium, zinc, lead, aluminum, tin, cadmium, porcelain, enamel, oxide layer, etc.
N represents Non ferrous non-ferromagnetic matrix, and the N-type coating thickness gauge adopts the principle of eddy current; To measure enamel, rubber, paint, plastic layers, etc. on substrates such as copper, aluminum, zinc, tin, etc. using eddy current sensors.
The FN type coating thickness gauge adopts both electromagnetic induction principle and eddy current principle, and is a two in one type coating thickness gauge of F and N types.
What are the daily maintenance and upkeep methods for coating thickness gauges?
We all know that a coating thickness gauge is a precision instrument, and to ensure the accuracy of the measured coating thickness, it is essential to ensure that the coating thickness gauge can always be in good working condition, and daily maintenance and upkeep are essential. The proxy expert of Yigao coating thickness gauge will briefly introduce how to maintain and maintain the coating thickness gauge.
Firstly, it is necessary to keep the coating thickness gauge clean, pay attention to heat and moisture resistance, and prevent contact with corrosive liquids or gases. During use, it is strictly prohibited to pull the probe wire and shake it randomly. For coating thickness gauges that have not been used for a long time, attention should be paid to removing the battery to avoid damage to the instrument caused by battery decay. Secondly, when installing the battery, it is necessary to confirm whether the positive and negative contacts of the battery are good, whether the voltage is normal, and pay attention to using the correct method when measuring. If there is a malfunction in the coating thickness gauge after installation, it is not advisable to disassemble it without authorization. It is necessary to promptly send it back to the manufacturer or a professional repair agency for repair.
