The Endress+Hauser FTL51B-3M7P50 is a compact, 2-wire vibrating fork level switch designed for reliable point level detection of liquids and solids. It features 316L stainless steel wetted parts, operates on a 24V DC, 2-wire loop, and provides a switching signal (PNP/NPN) for alarm or control functions. Its simple installation, lack of moving parts, and insensitivity to material properties make it ideal for high or low-level detection in tanks, silos, and pipelines.
