Operating
6.4 Operation with IO-Link - Advanced calibration
Switchpoint setting - Interface detection
Sensor behaviour:
Material 1 (Liquid A or foam) covers the probe: Out 1 and Out 2 do not detect this material.
Material 2 (Liquid B) with higher dielectric constant than material 1 covers the probe: Out 1
and Out 2 detect this material.
① Out 1, covered probe (Liquid B)
② Out 1, uncovered probe*
③ Out 2, uncovered probe*
④ Out 2, covered probe (Liquid B)
* For interface measurement "Uncovered probe" relates to a probe covered by Liquid A or foam
The diagram shows:
• Out 1 set to FSL
• Out 2 set to FSH
• 1 = contact closed
• 0 = contact open
