             JWH-A Magnetic Particle Flaw Detector for Parts of the Ring

Applicable scope

It is suitable for various parts of the ring both inside and outside surface of the magnetic particle testing.

Features and Technical parameters

1. The composite magnetization mode by the circular magnetization of opening and closing coils and the inductive method of longitudinal magnetization meet the full magnetization testing requirements of the ring parts
2. Detecting work-pieces can rotate horizontally to facilitate the observation and local focus magnetization.

3.  Opening and closing coils using silver-plated contacts and strong locking mechanism, which is reliable and long life to work

4. Semi-automatic PLC control the whole process of detecting, which is simple to operate
5. Adopting attenuation measure of magnetization current’s difference value and has little residual field.
6. Magnetization mode: Compound Magnetic Field.
7. The maximal peak value current of circular magnetization: 0-6000A continuously adjustable.
8. Longitudinal magnetization MMF: 0-12000AT continuously adjustable.
9. Detecting sensitivity: Clearly displays the artificial faults of A1 standard test piece 15／50

<>10.Residual Field: ≤0.3mT(240A/m)
