D型探头
Type D probe
D型探头：也称电磁轭探头，多种活动关节，磁化强度大。极距：60-220㎜，提升力：ac≥5㎏，dc≥18㎏；重量：2.5㎏.独立利用这种探头制成的设备叫电磁轭探伤仪，探头具有导磁高、磁化强度大等特点。
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.
