Measurement of outer diameter at multiple locations on a thin target

Example Application: Outer diameter measurement of injectors at multiple points

Optimal measurement system

Optimal measurement system2D Thrubeam Optical Micrometer

The 2D optical projection method makes it possible to measure the outer diameter of multiple points as well as the minimum/maximum values over specified ranges.

KEY POINTS

Even if the target is tilted, outer diameter can be measured accurately by utilizing the position correction function.

2D Telecentric Optical Method. Simultaneous measurement of up to 100 with calibrated high-speed measurement.

Measurement of outer diameter on thick targets

Example Application: Outer diameter measurement of large steel pipes

Optimal measurement system

Optimal measurement systemThrubeam Optical Micrometer

Outer diameter is measured by placing a target between two sensor heads.

KEY POINTS

Parallel alignment of the sensor heads is important to prevent values from changing if the target moves to the left or right.
