Y-7

AC/DC Electromagnetic Yoke

The Y‑7 is a high-performance AC electromagnetic yoke designed for non-destructive testing using magnetic particle inspection (MPI). It supports both AC and pulsed DC operation, providing strong and versatile magnetic fields for detecting surface and near-surface flaws on ferromagnetic components.

Features

Dual-power capability: Supports both AC and pulsed DC currents for flexible use
High magnetic strength: Delivers deep and surface-level inspection sensitivity
Ergonomic design: Lightweight, well-balanced housing enables single-handed operation
Articulated pole legs: Adjustable spread fits complex geometries and weld profiles
Integrated demagnetization: Enables field demag functionality after inspection
Tough build: Durable, sealed casing suitable for industrial environments
Traceability-ready: Individual serial number for equipment tracking

Applications

Ideal for:

MPI of welds, shafts, flanges, and castings in-field or in-shop
Detection of fatigue, grinding, quenching cracks, seams, and subsurface defects
Inspections in confined or hard-to-reach areas
Suitable for aerospace, automotive, energy, and maintenance industries
