O型探頭
Type O probe
O型探頭：也稱環形探頭，內徑:150㎜,中心磁場≥180oe.重量:2.5㎏.獨立利用這種探頭制成一臺設備叫環形探傷儀，它是利用線圈通電時產生強磁場的原理設計的，適用于軸棒類、管道類、葉片類等復雜工件的分段探傷或退磁。
Type o probe: also known as annular probe, with an inner diameter of 150mm, a central magnetic field ≥180oe, and a weight of 2.5kg. a device independently made of this probe is called annular flaw detector. it is designed based on the principle of generating a strong magnetic field when the coil is energized, and is suitable for segmented flaw detection or demagnetization of complex workpieces such as shaft rods, pipelines, blades, etc.
