A 6.4 Measurement
A 6.4.1 General
A 6.4.1.1 Measurement Mode
MEASMODE DIST_DIFFUSE|DIST_DIRECT|THICKNESS|VIDEO
- DIST_DIFFUSE: Displacement measurement in diffuse reflection; peak selection, see Chap. A 6.4.1.2
- DIST_DIRECT: Displacement measurement in direct reflection; peak selection, see Chap. A 6.4.1.2.
- THICKNESS: Thickness measurement
- VIDEO: Video transmission. Only the activated video data is transferred, no measurement values. Video images must be requested
through individual command, see Chap. A 6.5.2.6.
When selecting “DIST_DIRECT“ and/or „THICKNESS“ direct reflection mode must be activated so the sensor can switch over to
proper correction table. As a result, necessary corrections of measurement signal in direct reflection are done.
When selecting thickness measurement program, thickness 1, 2 and peak 1 and 2 are automatically chosen via Ethernet interface for
measurement value output. In measurement output via RS422 only the thickness is automatically output, the selection of 1
st
and 2
nd
peak is possible by means of OUTDIST_RS422.
A 6.4.1.2 Selection of Peak for Displacement Measurement
MEASPEAK DISTA | DISTW | DIST1
- DISTA: Output of peak with highest amplitude (standard for diffuse reflection)
- DISTW: Output of peak with largest area
- DIST1: Output of displacement 1 (complies with backside fading out for diffuse reflection)
A 6.4.1.3 Video Signal Request
GETVIDEO
Request of video signal via Ethernet interface.
A 6.4.1.4 Measuring Rate
MEASRATE 1.5|2.5|5|10|20|30|49
Selection of measuring rate in kHz. At 49 kHz a damping of measurement range takes place.
