To perform magnetic particle inspections conveniently, HANDY MAGNA is an excellent means. Simply contacting magnetic poles directly with inspection objects and applying magnetic particles with the switch held down detects any defects easily. Various types are provided to satisfy inspection requirements.
Portable Electromagnet Yoke
Models
Standard type. Mainly used for welding. With an universal yoke.
Small and compact type of A-1 type. Useful for long time inspections. Universal yoke is an option.
Variable yoke type. Used for multi-purposes and applications.
Small and compact type of A-4 type.
Spot type. Ideal for local inspections and for carrying.
Model TE-3 is the best for a turbine blade inspection.
Compact and lightweight for fillet weld
Compact and lightweight
Configuration
- Body (with a micro switch)
- 5m power cable (3-core, two-type rubber cap tire cable)
- Steel carrying case
Features
- The AC continuous method achieves higher ability to detect any surface defects by the skin effect.
- The yoke type, which suppresses a current flowing directly into the tested objects, avoids any possibility of sparking.
- Small, compact, and 100V power supply (AC) suitable for portable use.
- Yokes allow the user to use HANDY MAGNA for any shape tested objects.
- Water-proof switches minimize risks of rare short or shocks to human bodies when wet particles are used.
- For A-1, A-2, and A-6, their bodies have been connected directly to cable connection so that their strength and water-proofing property are improved.
