D型探頭
Type D probe
D型探頭：也稱電磁軛探頭，多種活動關節，磁化強度大。極距：60-220㎜，提升力：ac≥5㎏，dc≥18㎏；重量：2.5㎏.獨立利用這種探頭制成的設備叫電磁軛探傷儀，探頭具有導磁高、磁化強度大等特點。
D probe: also known as electromagnetic yoke probe, with various movable joints and high magnetization. Pole distance: 60-220㎜, lifting force: ac≥5㎏, DC ≥ 18 ㎏; Weight: 2.5㎏ The equipment independently made of this probe is called electromagnetic yoke flaw detector. The probe has the characteristics of high magnetic permeability and high magnetization.
