max. possible material buildup
Interface
detection
• Ignoring liquid A / detecting liquid B
• Ignoring foam / detecting liquid
Immerse sensor in liquid A or foam
Select the switchpoint adjustment according to the application as follows:
1. Ensure material level is
well below the probe
The unit will calibrate to an uncovered probe.
2. Set to high sensitivity
