随着科学技术的发展,金属材料的表面保护也越来越为重要。为了准确地测量各种涂层,我厂试制了一具袖珍涂层测厚计。该测厚计精度高,结构简单,使用方便,较目前国产的7502磁蜗流测厚仪有突出的优点。它由磁棒和软铁针组成;磁棒为永久磁铁,软铁针为坡膜合金,其两部分连成一体,通过磁棒的磁力作用,产生信号跳动,显示出膜层的厚度数。它的外
With the development of science and technology, the surface protection of metal materials is also more and more important. In order to accurately measure a variety of coatings, I plant trial production of a pocket thickness gauge. The thickness gauge of high precision, simple structure, easy to use, compared with the current domestic 7502 Magneto Flow Thickness Gauge has outstanding advantages. The utility model is composed of a magnet bar and a soft iron needle. The magnet bar is a permanent magnet and the soft iron needle is a slope film alloy, and the two parts are connected together. The magnetic force of the magnet bar generates the signal beating and shows the thickness of the film layer. It’s outside
