励磁系统测量板

磁性测厚仪工作原理是利用磁性测厚仪测量块或磁性探头与铁磁性材料基本之间的吸力大小与两者之间的距离成一定比例，该距离就是非铁磁性（包括导电与非导电）或者与基体导磁率相差足够大的覆层厚度。

目前，市面上常用的磁性测厚仪应用的是磁感应原理。它是基于利用探头经过非铁磁性覆层进入铁磁性基体的磁通大小来测定涂膜厚度，也可以测定阈值对应的磁阻大小来表征覆层厚度。当探头与涂层接触时，探头和磁性金属基体构成一闭合磁路，由于非磁性覆盖层的存在，使磁路磁阻变化，通过测量其变化可计算覆盖层的厚度。

励磁系统测量板是励磁调节器的重要组成部分，用于测量励磁调节器的功率柜输出电压、电流等参数，以确保励磁调节器的正常运行。

励磁系统测量板通常由专业的生产厂家提供，不同厂家生产的测量板可能存在一定差异，因此选择合适的测量板需要考虑其品牌、型号、规格、输出频率、物料编码等因素。

此外，励磁系统测量板在使用过程中需要注意维护和保养，如定期检查测量板的连接线路是否松动或断路，及时清理测量板表面的灰尘和污垢等。

Excitation system measurement board

The working principle of the magnetic thickness gauge is to use the magnetic thickness gauge to measure the size of the suction between the block or magnetic probe and the ferromagnetic material in proportion to the distance between the two, which is the thickness of the coating layer that is non-ferromagnetic (including conductive and non-conductive) or has a large enough difference with the permeability of the matrix.

At present, the magnetic thickness gauge commonly used on the market applies the principle of magnetic induction. It is based on the use of the probe through the non-ferromagnetic coating into the ferromagnetic matrix to determine the thickness of the film, can also determine the threshold corresponding to the magnetoresistance size to characterize the thickness of the coating. When the probe is in contact with the coating, the probe and the magnetic metal matrix form a closed magnetic circuit. Due to the presence of the non-magnetic covering layer, the magnetic resistance of the magnetic circuit changes, and the thickness of the covering layer can be calculated by measuring the change.

The excitation system measurement board is an important part of the excitation regulator, which is used to measure the output voltage and current of the power cabinet of the excitation regulator to ensure the normal operation of the excitation regulator.

Excitation system measurement boards are usually provided by professional manufacturers, and there may be some differences in the measurement boards produced by different manufacturers, so the selection of the appropriate measurement board needs to consider its brand, model, specification, output frequency, material code and other factors.

In addition, the excitation system measurement board needs to pay attention to maintenance and maintenance during use, such as regularly checking whether the connection line of the measurement board is loose or broken, and timely cleaning the dust and dirt on the surface of the measurement board.
