An overview of Electromagnetic AC/DC yoke
Handy Magna Yoke Model HCDX-Y7T, charging type magnetic particle flaw detector has the characteristics of compact structure, reasonable layout, small size, light weight and convenient portability. The flaw detector can be used directly in alternating current, and can also be used for AC magnetization power supply (AC battery pack) and DC magnetized power supply (DC-AC inverter battery pack), which is efficient and portable. It is suitable for hull weld inspection, high altitude steel structure weld detection and pressure vessel internal operation. This instrument is suitable for steel structure parts of power, metallurgy, petrochemical, machinery and other industries, such as boiler, pressure vessel, pressure pipe, ship body weld and welding structure of various types of ferromagnetic material surface and magnetic particle flaw detection of near surface defect.
This instrument conforms to the standard requirements of JB/T7411-2012, ASME BPVC,ASTM E709,ASTM E1444,ASTM E3024."electromagnetic yoke flaw detector technical condition".
Product features
Complete Sealed, durable construction
Chemical and abrasion resistant
DC-AC inverter battery design,AC and DC operation options for surface and sub-surface inspection
Exceeds ASTM lifting specifications
The three modes of power supply can be freely chosen:
There are places directly connected to AC power supply, which can be directly connected with AC power supply.
It is possible to use AC magnetized power supply (DC-AC inverter battery pack) to supply AC power without any direct insertion to AC power supply.
The DC magnetizing power supply (DC battery pack) can be used to realize the DC magnetization function.
AC magnetizing power supply (DC-AC inverter battery pack) has the functions of voltage regulation, overcharge, over current and over discharge.
When the lifting force is not enough, the power is automatically cut off to ensure the sensitivity of flaw detection.
The power display function can display the current battery power, and has the function of sound and light alarm.
Built in microcomputer chip to stabilize output voltage and ensure detection sensitivity.
Adjustable magnetization
Special working waist bag can carry battery pack, magnetic suspension, contrast agent, yoke probe, etc.
