电压-频率转换(以下简称V-F转换),是模数转换的常用方法之一。近来已有不少文章建议把它用于直流磁场的测量,并介绍了一些相应的测磁专用仪器——数字磁通计。我们利用V-F转换法测量了一台大型电磁分离器磁场的相对分布。在测量精度方面达到了满意的结果。 Voltage-frequency conversion (hereinafter referred to as V-F conversion), is one of the common methods of analog-to-digital conversion. Recently, many articles have suggested that it be used for DC magnetic field measurement, and introduced some of the corresponding magnetic measuring instrument - digital flux meter. We use the V-F conversion method to measure the relative distribution of a large electromagnetic separator magnetic field. In the measurement accuracy to achieve satisfactory results.
