Combines the lightweight JAYSON yoke with the AC ‘EASY’ Powerbelt to form a battery-powered, lightweight, electromagnetic AC yoke for Magnetic Particle Inspection.
JAYSON-PAC Battery Operated Lightweight AC Yoke
The Johnson & Allen JAYSON-PAC yoke is a battery-powered electromagnetic AC yoke for Magnetic Particle Inspection. The JAYSON-PAC yoke is ideal for portable inspections and rope work due to its light weight and its low current draw meaning portable yoke battery packs will last longer per charge.
Using the market proven JAYSON yoke as a base, Johnson & Allen researched and developed ways of making it portable. Unwilling to retreat from this task and using DC yokes as an easy way out, Johnson & Allen sought a way of maintaining the sought after ‘skin effect’ created by AC yokes while still having the unit powered by a lightweight battery – The skin effect producing the highest levels of defect detection clarity for surface and near surface defects. The result was the ‘AC-EAZY’ Powerbelt; A tool-belt design that can convert 12V DC into 110V AC.
The wave form generator in the JAYSON-PAC produces a stable supply that closely mimics a normal mains AC supply as opposed to using pulsed DC which generally gives a lower level of inspection clarity. The generator also features auto-sensing functionality which will supply the correct voltage to the yoke when loaded.
The wave form generator connects to the battery via a heavy duty snap on T connector which is quick to remove when necessary. For customers with older generation wave form generators, a T connector cable adaptor is available to connect to the latest battery.
The Jayson-Pac yoke has a number of features that make it a versatile and reliable tool for NDT. These features include:
- Lightweight yoke (Jayson yoke = 2.7kg)
- A stable supply that closely mimics a normal mains AC supply as opposed to using pulsed DC which generally gives a lower level of inspection clarity.
- Auto-sensing functionality which will supply the correct voltage to the yoke when loaded.
- A thick steeple jack type leather belt for incredible hard wearing with a long product life.
- A battery that holds enough charge for a full 8 hour shift on a single charge.
- Additional pouches available.
