CONTOUR PROBES
The B310, B310S and B142 Contour Probes are rugged high performance instruments for
Magnetic Particle inspection to accepted Non-Destructive 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 B310, B310S and B142 produce strong constant AC fields.
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 9 inches (228.6 mm). All 310 series
Contour P
robes come equipped with a 10’ (3.048 m) power cord.
The B310 is for use on 115 VAC 60 Hz, single phase grounded power source. Using an approved
GFCI is recommended.
The B310S is for use on 230 VAC 50-60 Hz, single phase grounded power source. The B310S 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.
The B142 is for use on 42-48 VAC 50-60 Hz, single phase grounded low voltage power source.
The B142 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.
