NM01DA1500DR

The Parker Research DA-1500-DR Portable Magnetic Inspection Unit is a robust and high-output power pack specifically engineered for conducting magnetic particle inspections (MPI) in diverse industrial settings. The "-DR" suffix denotes a significant feature: an integrated digital LCD display that provides a clear and precise readout of the output current, ensuring accurate and repeatable inspection procedures regardless of ambient lighting conditions.  

This unit is designed to deliver substantial magnetic field strength through the test piece, offering both Alternating Current (AC) and Half-Wave Direct Current (HWDC) magnetization capabilities, each with a maximum output of approximately 1500 Amperes. The actual current achieved will depend on factors such as the length and gauge of the connecting cables and the impedance of the test piece.  

Key Features and Operational Aspects:

• Dual Output Capability (AC & HWDC):

  • Alternating Current (AC): Excels at inducing a magnetic field concentrated at the surface of ferromagnetic materials. This makes it highly effective for detecting surface-breaking discontinuities such as fine cracks and fatigue fractures. Additionally, the alternating nature of the current allows for effective demagnetization of inspected parts.  

  • Half-Wave Direct Current (HWDC): Offers enhanced penetration of the magnetic field into the subsurface of the material compared to AC. This makes it more suitable for detecting certain types of near-surface flaws and is particularly useful for inspecting welds and castings.  

• Precise Digital Current Control: A user-friendly control knob located on the front panel allows for infinitely variable adjustment of the output current from zero to the maximum rated value. The prominent digital LCD meter provides a direct and unambiguous display of the selected current level, enhancing accuracy and repeatability in inspection settings.  

• Simple Field Selection: The choice between AC and HWDC magnetization is easily made by connecting the appropriate field cables to designated connectors on the unit.  

• Engineered for Portability and Durability: The DA-1500-DR is built to withstand the rigors of demanding field and shop environments. Its robust construction and protective casing ensure longevity. For ease of transport, it is equipped with both a rear carrying handle and a front swivel handle. The front handle can also be conveniently used as a prop to tilt the unit upwards, improving visibility of the control panel and digital display.  

• Versatile Magnetization Techniques (with optional accessories): The unit can facilitate various magnetization methods, including:

  • Direct Contact (Prods): When used with optional prod sets connected to the output cables, the unit can pass current directly through a localized area of the test piece, inducing a circular magnetic field ideal for detecting linear flaws oriented transverse to the current flow.

  • Coil Magnetization: By wrapping the output cables around a component, the unit can induce a longitudinal magnetic field, which is most effective for detecting flaws oriented circumferentially or transverse to the length of the part.  

• Integrated Demagnetization: The AC output function can also be utilized to effectively demagnetize ferromagnetic components after the completion of the magnetic particle inspection process, which is often a critical requirement.  

• Power Input Flexibility: The DA-1500-DR is available in different voltage configurations to suit various power supply standards, typically offered in 230VAC or 460VAC, single-phase versions (the specific voltage requirement must be specified at the time of order).  

• Warranty Assurance: Like other Parker Research products, the DA-1500-DR is typically backed by a manufacturer's warranty, providing assurance of its quality and reliability.
