CDX-V  Multi-functional Magnetic Particle Detector

I. Brief Description

CDX-V is a new modified, full-electronic control magnetic-particle fault localization equipment made by our Company on the basis of CDX-IV model with well-chosen new materials and technology by utilizing the advantages of its counterpart at home and abroad is featured by complete functions, quick fault detection, high sensitivity, ease of operation, lower rate of failures and easy maintenance. The instrument adopts the magnetization process by additional magnetic field and boasts small volume, light weight and portability. Its highly integrated electric circuit makes one instrument perform all the functions of several ones. It can be fitted with four probes of A, D, E & O with adjustable output current to meet the requirements for different sensitivity. Besides, it also has a power phase controlled circuit breaker in AC magnetization in addition to overload protection and demagnetization function.

Selection of probe:

►A type probe: also named horseshoe magnetic yoke probe or fillet weld probe, turning joint angular magnetic head, which is fitted with a working lamp and is especially suitable for fault detection of work pieces with abnormal face and complicated shape. Polar distance: 20-160㎜;lifting power: AC≥5㎏,DC≥18㎏;weight : 1㎏. The equipment made by using this probe is referred to as horseshoe magnetic yoke detector or fillet weld detector. The probe finds wide application as it uses the turning joint.

►D type probe: also called electromagnetic yoke probe with various turning joints and great magnetization strength. Polar distance:60-220㎜; lifting power: AC≥6㎏,DC≥18㎏; weight: 1.6㎏.The equipment made by using this probe independently is named electromagnetic yoke detector and the probe is featured by high magnetic inductivity and great magnetization strength. 

►E type probe: also called cross magnetic yoke probe or rotating-field probe and can conduct omnibearing combination magnetization flaw detection at a time. The running roller and working lamp can increase the fault detection speed. Polar distance: 110㎜,lifting power: AC≥9㎏ and weight:2㎏. The equipment made by using this probe independently is called rotating-field fault detector, which uses two cross magnetic yokes and AC move-phase technology to produce a synthetic rotating field that varies with time for omnibearing combination magnetization of a work piece at a time. The fault detection is done quickly with high inspection quality. 

►O type probe: also called ring probe with an internal diameter of 150㎜ and center field ≥180Oe.Weight:3㎏.The equipment made by using this probe independently is named ring fault detector. It is designed on the principle of forming a strong magnetic field by energizing a coil and is suitable for sectional fault detection or demangnetization of complicated work pieces including axles, bars, pipes and vanes.
