                        根據測量不同的磁鋼,測試線圈選擇時應該注意以下幾點

                        2019-05-14

                        1.亥姆霍茲線圈筒內徑要大永磁鐵氧體于被測樣品最大外徑

                        2.徑向60%D(D為亥姆霍茲線圈直徑)

                        3.縱向70%H(H為亥姆霍茲線圈高度的1/2)

                        4.檢測值的重復性要磁鋼廠家有可行性驗證

                        5.亥姆霍茲線圈匝數

                        6.線圈線徑的選擇

                        只要注意以上幾點,對磁體、磁器件、磁產品的磁通測量,如果用磁通計/磁通表測量,磁通測量就離不開測量線圈或測試夾具,對獨立的磁鋼而言,用同類線圈或夾具,測量的磁通值的重復性是很好的,比對性很強.
