Parker Research Corp B300-MR Series Operating Instructions

The B300-MR Contour Probe is a rugged high performance instrument 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. Model B300-MR produces a strong constant AC 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" (304.8mm). The B300-MR series
Contour Probe comes equipped with a 10' (3.048 m) power cord.
The B300-MR contains electronic circuitry that is sealed within the instrument's housing. The
external push button switch magnetically activates the power circuit from the outside. There is
no electrical contact between the switch and internal circuit. This instrument is ideally suited for
high moisture areas.
The B300-MR Contour Probe has an IP65 rating.
This instrument is not water proof and should never be submerged
The B300-MR is for use on 115 VAC 60 Hz, single phase grounded power source. Using an
approved GFCI is recommended.
The B300-MRS is for use on 230 VAC 50-60 Hz, single phase grounded power source. The
B300-MRS 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.
