1.7 Measuring an External Radius with K-METRON.

It is straight forward to measure external radii down to 5mm. Place the sensor head on the

surface of the part located at external radius to be measured. Ensure that the sensor head is

perpendicular to the tangent of the radius to make an accurate reading.

1.8 Measuring an Internal Radius with K-METRON.

It is straight forward to measure external radius down to 5mm. At radii less than this the

main difficulty is with access to the surface. When measuring thickness of internal radii, the

correct measurement often requires compensation for the gap distance as shown below.

Thickness displayed on the meter

will be the thickness of the

measured part plus the gap

between the sensor head and the

part.

A minimum external radius of 5mm

(3/16") can be measured using the

supplied 10mm diameter magnetic

sphere.

A minimum external radius of 3.3mm

(0.1229") can be measured using a 6.6mm

diameter magnetic sphere (contact for

supply).

A minimum internal radius of

25mm (1") can be measured before

it becomes impractical and difficult

to compensate for gap distances.

Radii less than 25mm also tend to

allow the magnetic force to pull

the magnet to the side of the part.
