This means that Gz/Gx also defines the:
• minimum object height to be detected reliably
• minimum object width to be detected reliably
The height profiles are internally detected by the sensor with a higher
resolution than Gz/Gx� Changes in object height/width can therefore be
detected within the measurement uncertainty�
3.3 Applications
The photoelectric sensor is particularly suitable for process quality assurance,
more precisely monitoring of workpiece shapes and fault detection�
Examples:
-Monitoring of the processing quality, e�g� diameters of drill holes�
-Check of workpieces for faulty processing, e�g� missing drill holes�
