LCD series spark detector is based on the need to design waterproof corrosion thickness for the insulating layer of tiny defect detection metal substrate, such as glass-lined coat, fiberglass, epoxy coal tar, rubber lining of pinholes, bubbles and crack, widely used in chemical, petroleum, rubber, ceramic and other industries. The instrument is an essential tool that you use to detect corrosion coating quality. Technical Parameters: LCD-3 detector thickness: 0.1 ~ 20mm high voltage output: 5KV ~ 30KV power supply: DC · 12 V Power: 6W Volume: 180 × 170 × 70 operation method (mm) Thickness: 1. zero, That is upregulated in particular zero-zero thickness plate, or in the original substrate to be measured increases to zero; 2 Depending on the measuring range of measurement products, with the appropriate test piece transfer value to reduce measurement errors. Under this method in general, or when there is no problem using a newly purchased equipment, just a little more complicated. But when the probe is used for some time, the problem came out. Operation in our measurement precision is greatly reduced. Difficult to grasp. The reason is that the principle of the product, which is a fatal flaw that the probe is to use a magnet around the coil. Generating a magnetic field through the current high-precision thickness gauge after the magnetic field is irregular. Fortunately eddy current thickness, there is now a new type of coating thickness gauge, which uses the latest magnetic induction technology. This is what we know of the Hall effect, Hall discovered in 1879. By studying the relationship between the Hall voltage and the operating current measured electromagnet magnetic permeability relationship between the Hall voltage and the magnetic field, Hall found that the potential difference UH IH and the current strength is proportional to the magnetic flux density is proportional to B, d is inversely proportional to the thickness of the sheet. This field is to become the rule. The principle used in the coating thickness on top of it without having to re-tune the test piece. Especially when measured arc or concave product even easier to use and convenient. Instrument gage Branch of the Instrument (certified), thickness provided by the Qingdao Branch of the Instrument Co., Ltd. Qingdao Branch of the Instrument Co., Ltd. (www.qdjk17.com) is in Qingdao, Shandong analysis instruments leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Branch of the Instrument in leadership with the staff warmly welcome all inquiries negotiations to create the Branch of the Instrument better future.
