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 Probes 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.

GENERAL SAFETY RULES

Please read all instructions. Failure to follow all instructions listed below may result in injury. If the

equipment is used in a manner other than as specified in these operating instructions, the

protection provided by the equipment may be impaired. Always wear eye protection

DO NOT OPERATE unit from a DC power source.

Do not abuse the power cords. Never carry the instrument by the cord or attempt to unplug the

instrument using the cord. Always operate the instrument with the standard installed cord.

Changing or using a damaged cord can increase the risk of electrical shock. The cord should be

checked periodically for any damage.

Do not position the instrument such that it would be difficult to operate the disconnect device (plug)

on the end of the power cord.

The outside housing should remain intact and solid. Any damage, chipping, or separating

exposing internal wires is a hazard. Instruments should not be used in this condition. The outside

housing should be periodically checked for damage.

Duty Cycle: The 310 series are designed for a 50% duty cycle. Continuous operation may cause

overheating and damage the Contour Probe.

Operating Environment: Temperature: 32° to 104°F (0° to 40°C). Relative humidity: 10% to 95%,

non-condensing.

Shipping and Storage Environment: Temperature: 40° to 140°F (4.44° to 60°C). Relative

humidity: 5% to 95%. Vibration and shock: As encountered in normal shipping and handling with

no degradation

General Cleaning

The outside surface of the instrument can be periodically wiped with a clean cloth and a mild

general purpose cleaner. Avoid using cleaners such

as lacquer thinner, or mineral spirits that could

damage the outside housing.

Never attempt field service. All 310 series contour

probes should be returned to the factory for repairs.

OPERATION: Connect the instrument plug into a

Grounded power outlet of proper voltage. Place the

Contour Probe legs upon the work surface with the

suspected defect at right angles to the legs (Good

contact will produce the best results). Push the test

switch to energize the instrument. Lightly dust or

float dry magnetic inspection powder over the area

being inspected. Defect indications will be revealed

in a direction shown on figure 2. Turn the Probe 90

degrees from the first test and repeat the process.

This method may also be utilized when applying a

wet medium. Check all procedures and standards for further details involving inspection specifics.

DEMAGNETIZATION: Small pieces, which have become residually magnetized, may be easily

demagnetized by the following procedure: Energize the Probe and pass small parts through the

area between the leg ends “feet” and withdraw to a distance of approximately two feet. On large

pieces, place the Probe in the same position as inspection, energize the Probe and lift from the

work surface to a distance of approximately two feet. This procedure may need to be performed

more than once to remove the residual field.

A.C. MAGNETIZATION: An A.C. magnetic field induced into a part is a “skin” or surface field and

does not penetrate the cross section of the material. A bi-product of A.C. is in the form of eddy

currents. These eddy currents tend to guide or direct the magnetic field in a narrow pattern

between the poles. Another bi-product is a vibratory action, which adds mobility to the inspection

particles to form a more highly defined powder build-up at the defect. For these reasons, an A.C.

magnetic field is the most desirable for the detection of surface breaking defects.

CAUTION: Small parts may become magnetically saturated due to excessive field application.

This may cause a masking effect to the point where it is impossible to define a defect.

WARRANTY: The Parker 310 series are warranted against malfunction due to defective material

and or workmanship. The defective unit will be repaired or replaced (less incoming freight charges)

for a period of one year from the date of sale. This repair warranty does not apply to altered units.

Repair or replacement of the defective unit will be made at the discretion of Parker Research

Corporation. Repaired or replacement unit(s) will be returned to the original customer prepaid.

The obligation of Parker Research Corporation is limited to the repair or replacement of the

defective unit. No other obligation is expressed or implied. Parker Research Corporation assumes

no liability from any claim arising from the use of this equipment.

CAUTION: For the correct and safe use of this equipment, training of operating personnel is

required. Use of proper inspection procedures, standards compliance and safety requirements is

the obligation of the user.

ALWAYS WEAR SAFETY GLASSES WHEN USING THIS EQUIPMENT
