Application Examples HBLC and HBSLC
HBLC consist of a PTFE covered rod and requires a electrical connection to the overflow pipe or to the pipe segment where
it is installed. The sensor is more sensitive to turbulent conditions but with a high filter time it is able to control the level
even in turbulent conditions. The simple design is less sensitive to contamination compared to HBLT.
