CONTOUR PROBES
The
400 Series
Contour Probes are rugged high performance instruments for Magnetic Particle
inspection to accepted Nondestructive testing standards. Certain operating procedures and safety
precautions should be observed.
INSTRUMENT DESCRIPTION:
Basically, the Contour Probe is an electromagnet producing a
strong magnetic field. Placement of the two poles (legs) upon ferrous metal provides a path for the
intense magnetic field to pass from one pole to the other. The part completes the flux path and
becomes highly magnetized. Models A410, A410S and A448 produce strong constant AC fields.
Electronic circuitry contained within the molded housing of the DA400 and DA400S models permits
selection of a strong constant AC field, or a high intensity half wave rectified (DC) field. All Parker
Contour Probes are designed with flexible legs that allow the field to be “focused” at a precise area
of inspection. The maximum leg spacing is 12 in. (304.8mm). All 400 series Contour Probes come
equipped with a 10’ (3.048 m) power cord.
The DA400 and A410 are for use on 115VAC 50-60 Hz, single phase grounded power source.
Using an approved GFCI is recommended.
The DA400S and A410S are for use on 230VAC 50-60 Hz, single phase grounded power source.
The DA400S and A410S are sold without a power cord plug. Only locally approved plugs should
be used and installed by certified personnel. Using an approved GFCI is recommended.
The A448 is for use on 42-48VAC 50-60 Hz, single phase grounded low voltage power source.
The A448 is sold without a power cord plug. Only locally approved plugs should be used and
installed by certified personnel. Using an approved GFCI is recommended.
