Magnetic Particle Inspection (MPI) Equipment

JAY Bi-Volt


230V & 110V NDT Yoke

The JAY Bi-Volt is similar to our single Voltage JAY but gives the operator the choice of using either 230V or 110V mains supplies. Operators simply connect one of the two leads supplied and inspect as they would normally. The JAY Bi-Volt produces identical magnetic fields when supplied with the same voltage as the standard JAY.

The JAY Bi-Volt is ideal for operators who do contract work who cannot rely on a single type of mains supply being available in every premise they visit.

*Note: The tangential extraneous magnetic field will vary depending on whether the yoke is energized in free space (unloaded) or when in contact with a part (loaded). Material properties and pole spacing will also alter the magnetic field. For this reason operators should not rely on field measurements alone as a performance check and should verify the lifting strength of the yoke with a 4.5kg test weight and use a QQI shim or flux indicator strip for evaluation before undertaking inspection.
