In my last blog, I told you about the restrictions we have with thick objects.
Here, I want to show you how to handle thick objects with full measurement performance.

• Circular Objects
• Right angle objects
• FAQ

Circular Objects

tubes, pipes, rods, balls

Example for circular tube:

Measuring the diameter of round tubes, even when thicker than specified in our instruction manual.

Due to the curved edges, we can measure the diameter precisely.

Condition: the center of the tube must remain in the 1/3 – 2/3 section.

Result:

Both edges can be measured with full performance.

Position & width  → with full resolution and high precision.

Right angle objects

plates or lying round parts

Example for a right angle box

In that case we can tilt the sender – receiver, so that we can measure one edge precisely (alternatively the box can be tilt).

Attention:  we only can reach a valid measurement for the upper edge - due to the angle of the crossed beam.

Of course, the measured edge must be positioned according to the 1/3 - 2/3 rule.
As you can see at the  bottom edge, we get invalid measurement due to the beam shadow at the back side of the box.
No width measurement!

Example for a hanging wheel rim

In that example we can measure precisely the height of the wheel rim.

FAQ

• Is width measurement less accurate then single edge measurement?
  Almost not.
• What tilt angle is needed for the position measurement of wheel rim in the example above?
  A small angle around 1…3° is enough due to the slight beam angle of crossed beams.
• How many tubes can be measured side by side?
  max. 5 – due to 10 edges
• How to configure width measurement via SOPAS?
  Function Configuration → allocating F1, F2, etc
• What can happen when the No. of tubes changes during process?
  the numeration of edges will change → loss of width measurement for the allocated functions
• How to solve that?
  You can solve this using search fields.
