How does a radiusometer work?
| The radius gauge works as a concave and convex reference device. It is used to clarify how closely the radius in question (on the workpiece) compares to the finely machined radii on the gauge. | |
| The light source should be placed behind the object being measured to help identify any gaps between surfaces. |
 | The finely machined sensor radius is pressed tightly against an object with a concave or convex radius. Two different measurement processes are described below. |
Concave Radius Testing | |
 | The radius gauge can be used to check the size of a concave radius on an existing object. |
 | Here, the outer convex radius of the gauge is used to define the inner concave radius of the sheet metal. |
Convex Radius Check | |
 | The radius gauge can be used to check the size of a convex radius on an existing object. |
 | Here, the inner concave radius of the gauge is used to determine the outer convex radius of the hinge. Both measurements correspond to the same measurement indicated on the instrument. |
