CDX-II multipurpose magnetic particle flaw detector
1. function
CDX-II multipurpose magnetic particle flaw detector is our newly-developed equipment for the testing of casting quality using magnetic particles. It is featured by complete functions, quick flaw detection, high sensitivity, ease of operation, lower rate of failures and easy maintenance. Its highly integrated electric circuit makes one instrument perform all the functions of several ones. It can be fitted with three types of probe-A, D, O and E with adjustable output current to meet the requirements for different sensitivity.
This machine adopts SCR trigger circuit. All electronic components are selected strictly, which ensures stable and reliable working performance and low failure rate. This machine outputs safety voltage, suitable for places which do not allow high voltage equipments.
1) A probe
It is also named horseshoe probe or weld probe and features a movable inclined magnetic head. It has one working lamp and is especially applicable for partial AC or DC flaw detection of interior/exterior angles of irregular surfaces and work pieces. The pole distance is 20-160mm; hoisting capacity: AC≥5kg and DC≥18kg; weight: 1kg. This kind of probe is adopted by the Horseshoe Magnetic Yoke Tester or Angle Weld Tester. It features a wide scope of application with the movable probe.
2) D probe
It is also called electromagnetic yoke probe with various turning joints and great magnetization strength. It can be used for AC or DC flaw detection of plane and curved surface work pieces. Polar distance:50-200mm; lifting power: AC≥6kg,DC≥18kg; weight:2.5kg.
3) O probe
It is also called ring probe with an internal diameter of 150mm and center field ≥180Oe.Weight:2.5kg. It is designed on the principle of forming a strong magnetic field by energizing a coil and is suitable for sectional fault detection or demagnetization of complicated work pieces including axles, bars, pipes and vanes.
4) E probe
It is also called cross magnetic yoke probe or rotating-field probe. Different from D-shaped and A-shaped probe, it can conduct omnibearing magnetization flaw detection at a time. The equipped working lamp ensures users to work with enough light; the equipped roller ensures easy operation and high working efficiency.
Polar distance: 110mm,lifting power: AC≥7kg and weight:3kg.
