QPP 2-Circuit current puls generators

Innovation in Non-Destructive-Testing

The devices of the QPP series allow for a cost effective and fail-safe magnetic particle test for surface defects (such as cracks, blowholes, or pores) of magnetizable material, reducing the required amount of expandable material at the same time.

Procedure:
The test method uses two current impulse channels, which alternately produce high-current pulses on separate outputs. Thus, two orientations of surface defects can be tested simultaneously.

Application:
The area of application covers inspection for surface defects on ferromagnetic steel parts, e.g. welded joints, cast and forged items, grinded surfaces, cold- and hot-formed parts, hardened parts, and more.

Benefits:

• Clear indication using DC current pulses, alternatively using AC pulses
• Reduction of false positives
• Simultaneous inspection for longitudinal and crosswise defects by using two independent current sources for magnetization (using current flow though the probe or coils, or a combination of both)
• Fast and efficient inspection of large structures and surfaces
• Simultaneous inspection of multiple parts
• Magnetization by current flow through the part or by use of coils, or by a combination of both methods
• Mobile inspection is possible even under cramped conditions
• Negligible generation of heat in the part under test
• No problems with residual magnetism after test
• Permanent surveillance of contact quality to avoid contact burn
• Combined measuring of test current and magnetic field for both output channels.
• Low energy consumption
• NEW: Demagnetiziation
