Technical Information Liquiphant T FTL0H Level limit switch Level limit switch for liquids in the foodstuff industry, compact design, housing made of corrosion-resistant stainless steel Application The Liquiphant T FTL0H is a level limit switch for liquids in storage tanks, agitators and pipes which have to meet particularly high hygiene standards internally and externally. It is used in particular in areas where other measurement methods would probably fail: e.g. in the event of viscosity, build-up, turbulences, flows, air bubbles, rash temperature change when cleaning. The Liquiphant T FTL0H is a hygiene version for fluid temperatures up to 50 C. Your benefits E.g. Stainless steel housing with round connector M x, degree of protection IP69K, always air-tight even in the event of hour-long overflooding and intensive cleaning External test option using test magnet On-site function control using external LED display Large selection of process connections for hassle-free installation in existing systems Easy to install even at points difficult to access due to compact design Rugged stainless steel housing (36L) CIP and SIP cleanability ensured EHEDG certification TI379F/00/en

Function and system design Measuring principle Measuring system The tuning fork of the FTL0H is brought to its resonance frequency by means of a piezoelectric drive. If the tuning fork is covered by liquid, this frequency changes. The electronics of the FTL0H monitor the resonance frequency and indicate whether the tuning fork is freely vibrating or is covered by liquid. The measuring system comprises: Liquiphant T FTL0H limit switch Progammable logic control (PLC), miniature contactor, solenoid valve or AS-i bus AS-interface U... PLC 3 ~ 30 V Example ): Overfill protection or top level detection Example ): Lower level detection or dry running protection Example 3): Dry running protection for pump L00-FTL0Hxx-4-05-xx-en-00 Endress + Hauser 3

By choosing the suitable operating mode (MAX or MIN safety), you ensure that the FTL0H switches safely even in the event of a fault (e.g. if the power supply line is disconnected). MAX - maximum safety The FTL0H keeps the electronic switch closed as long as the liquid level is below the fork. Example of an application: overfill protection MIN - minimum safety The FTL0H keeps the electronic switch closed as long as the fork is immersed in liquid. Example of an application: dry running protection for pumps The electronic switch opens if the limit is reached, if a fault occurs or the power fails. 4 Endress + Hauser
