The Endress+Hauser FTL51B-29FJ2/0 is a vibronic tuning fork point level switch dedicated to liquid medium limit monitoring, adopting piezoelectric resonance measuring principle. When liquid submerges the fork probe, vibration frequency attenuates, and internal electronics trigger switching signals for overfill prevention (MAX) or pump dry-run protection (MIN) logic.
