Quality control of rubber seals on the basis of height measurements

poscon hm

The measurement of object height is an important aspect in quality control applications. With the PosCon HM light-section sensor, Baumer says it offers a unique, compact measuring device for this kind of task.

The smart, pre-configured profile sensor offers five measurement modes for different measurement tasks. An exact positioning of the measured objects is not required.

The PosCon HM provides reliable measurements even on shiny and very dark surfaces. In conjunction with its high measuring accuracy of up to 2 μm, it is suitable for a large number of applications in at-line, off-line and in-line control.  Continue reading Quality control of rubber seals on the basis of height measurements

Aerotech demonstrates patent-pending motion control sensor

Aerotech has launched a motion control sensor with a parallel-kinematic design which provides unmatched geometric performance, says company, adding that it also offers superior positioning resolution and linearity with the direct-metrology capacitive sensor.

Aerotech’s QNP3 series XYZ piezo positioning stages combine sub-nanometer resolution, high dynamics, and excellent geometric performance in a compact three-degree-of-freedom (DoF) package.

They come with a 40 mm x 40 mm clear aperture with closed-loop travels up to 100 µm x 100 µm x 10 µm (open-loop travels to 120 µm x 120 µm x 12 µm).

The design is ideal for optical and scanning probe microscopy or other inspection or manufacturing applications where two-sided part access is required with three-DoF manipulation.  Continue reading Aerotech demonstrates patent-pending motion control sensor
