Liquiphant T FTL20. Technical Information. Level limit switch for liquids

Transcription

1 Technical Information Liquiphant T FTL0 Level limit switch for liquids Application The Liquiphant T FTL0 is a level limit switch for all kinds of fluids and is used in tanks, containers and pipelines. It is used in cleaning and filtering systems and coolant and lubricant tanks as an overspill protection or as a pump protector. The FTL0 is ideal for applications which previously used float switches and conductive, capacitive and optical sensors. It also works in applications which are unsuitable for these measuring methods due to conductivity, build-ups, turbulence, flows or air bubbles. The FTL0 is not suitable for hazardous areas and areas where the medium temperature is above 50 C. For hygienic areas the use of FTL0H is recommended. Your benefits Operational safety, reliability and universal applicability through use of the tuning fork measuring principle External test option using test magnet On-site control using external LED display Easy to install even at points difficult to access due to compact construction Rugged stainless steel housing (6L) Service-friendly plug-in connections For medium temperatures up to 50 C TI64F/00/en

3 Function and system design Measuring principle Measuring system The tuning fork of the FTL0 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 FTL0 monitor the resonance frequency and indicate whether the tuning fork is freely vibrating or is covered by liquid. The measuring system comprises: Liquiphant T FTL0 limit switch Progammable logic control (PLC), miniature contactor, solenoid valve or AS-i bus AS-interface U... PLC ~ 0 V Example ): Overfill protection or top level detection Example ): Lower level detection or dry running protection Example ): Dry running protection for pump L00-FTL0Hxx-4-05-xx-en-00 Endress+Hauser

By choosing the suitable operating mode (MAX or MIN safety), you ensure that the FTL0 switches safely even in the event of a fault (e.g. if the power supply line is disconnected). MAX - maximum safety The FTL0 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 FTL0 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
