QPP 2-Circuit current pulse generators

Description:

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.

Important note:
The suitability of QPP equipments has to be tested in every individual case in advance. Please contact us to arrange a personal appointment for demonstration.

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
  • Demagnetiziation
