optoNCDT 1420
A 4.2.2 Signal Processing
Measurement task Standard Suitable for materials made of ceramics, metal or filled plastics
Multi-surface
1
Suitable for e.g. Printed circuit boards (PCB) or hybrid materials
Light penetration
1
Suitable for plastics (POM, Teflon), materials with strong penetration of
the laser
Measuring rates 250 Hz / 500 Hz / 1 kHz /
2 kHz / 4 kHz
For light and matt measuring objects a high measuring rate may be
required. For dark or bright measuring objects a slower measuring rate
may be required (e.g. black lacquered surface) to improve the measu-
ring result.
Recording trigger /
Output trigger
Level Continuous measurement output takes place as long as the selected
level is applied. Level selection, see Chap. 7.3. Pulse duration must at
least be one cycle time. The subsequent break must also be at least one
cycle time.
Edge infinite Edge selection. „0“ end trigger, „1 ... 16382“ values per trigger, „16383“
infinite trigger
manual Number Value
Software infinite Software triggering is started by clicking the button Release trigger.
„0“ end trigger, „1 ... 16382“ values per trigger, „16383“ infinite trigger
manual Number Value
Inactive No triggering
Evaluation range Start of range 0 ... 99 % Value Set region of interest, i.e. only this range is used for measurement value
recording. „Start“ value must be smaller than „end“ value.
End of range (< 100 %) is set individually for the ILD1420-500 sensors.
End of range 1 ... 100 % Value
1) Available for the sensor models ILD1420-10/25/50.
