DA-750 High Amp Portable Magnetic Inspection Unit
The Parker
Research DA-750 magnetic inspection unit provides high output AC or HWDC
fields for magnetic particle inspection. Field selection is determined
by using the appropriate field cable connector. Current output is infinitely
variable from zero to maximum by use of the current control located on
the front panel, and is indicated by the panel meter. Actual current output
is determined by cable size and length. AC magnetic fields offer the best
sensitivity for detection of surface defect indications. Operates from either 115 VAC or 230 VAC (must be specified) The AC field is also beneficial for demagnetizing after inspection. Half-Wave DC magnetic fields provide for the detection of certain subsurface defect indications. DC fields penetrate a cross section of the test area rather than just the surface. Optional magnetizing cables can be equipped with prods for circular magnetization.
The cables can be wrapped around parts to form a coil for longitudinal
magnetization. Demagnetization is accomplished in a similar manner. |
