JAYSON
MAGNETIC PARTICLE INSPECTION YOKE
NDT Yoke
Manufactured in-house the JAYSON has a proven track record for usability, durability and reliability. The core is encapsulated in a hardwearing, impact and abrasion resistant polymer which makes the JAYSON hard wearing and the switch is positioned on the spine of the yoke to minimise the profile of the yoke. Like other Johnson & Allen yokes the JAYSON is fitted with a self-resetting thermal cut-out to prevent burnouts from misuse.
The JAYSON is supplied lift tested with certificate of conformity and in a heavy duty canvas bag as standard.
Available in 230V and 110V versions.
Replacement parts also available - Including pairs of complete leg sections, pairs of just the feet sections, micro switches, switch covers and rubber membranes etc.

*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.
